To draw a line graph, first draw a horizontal and a vertical axis. Age should be plotted on the horizontal axis because it is independent. Height should be plotted on the vertical axis. Then look for the given data and plot a point for each pair of values.

What are the 7 steps to drawing a line graph?
Terms in this set (7)
- identify the independent and dependent variables.
- determine the range of the data that needs to be plotted for each axis.
- choose the ranges for the axes.
- number and label each axis.
- plot the data points.
- draw the “best fit” line for the data.
- give the graph a title.
How do you graph straight lines?
Plotting straight line graphs
- Re-arrange equations into form y = mx + c.
- Pick 3 sensible points for x, including 0, then solve for y.
- Plot points on grid.
- Join with a straight line that goes through the y axis.
- Graph will cut the y axis at (0,c) and have gradient m.
What are the five parts of a line graph?
The following pages describe the different parts of a line graph.
- The Title. The title offers a short explanation of what is in your graph.
- The Legend. The legend tells what each line represents.
- The Source. The source explains where you found the information that is in your graph.
- Y-Axis.
- The Data.
- X-Axis.
How do you make a simple line graph?
Create a line chart
- Copy the example worksheet data into a blank worksheet, or open the worksheet that contains the data that you want to plot into a line chart.
- Select the data that you want to plot in the line chart.
- Click the Insert tab, and then click Insert Line or Area Chart.
- Click Line with Markers.
How can I draw a graph?
- Step 1: Identify the variables.
- Step 2: Determine the variable range.
- Step 3: Determine the scale of the graph.
- Step 4: Number and label each axis and title the graph.
- Step 5: Determine the data points and plot on the graph.
- Step 6: Draw the graph.
How do you draw a graph in math?
Have a go
- Click to see a step-by-step slideshow.
- YOU WILL NEED: A whiteboard.
- STEP 1 – Draw a table of values for the x and y coordinates.
- STEP 2 – Using the equation y = 2x + 1, calculate the value of y by using the x value in the table.
- STEP 3 – Draw a graph and label the x axis 1 to 4 and the y axis 1 to 9.
What is an example of a line graph?
A line graph is usually used to show the change of information over a period of time. This means that the horizontal axis is usually a time scale, for example minutes, hours, days, months or years. Example: The table shows the daily earnings of a store for five days.
What are 3 things a graph must have?
Essential Elements of Good Graphs:
- A title which describes the experiment.
- The graph should fill the space allotted for the graph.
- Each axis should be labeled with the quantity being measured and the units of measurement.
- Each data point should be plotted in the proper position.
- A line of best fit.
What is line graph in maths?
A line graph is a type of chart used to show information that changes over time. We plot line graphs using several points connected by straight lines. We also call it a line chart. The line graph comprises of two axes known as ‘x’ axis and ‘y’ axis. The horizontal axis is known as the x-axis.
What are the rules for drawing graphs?
- Main Idea. Supporting Details.
- Rules. Always title the graph with an appropriate name that explains the data shown.
- No Break Lines, evenly space the interval, and include labels (with units).
- No Break Lines, evenly space the interval, and include labels (with units).

How do you graph using Excel?
How to Make a Graph in Excel
- Enter your data into Excel.
- Choose one of nine graph and chart options to make.
- Highlight your data and click ‘Insert’ your desired graph.
- Switch the data on each axis, if necessary.
- Adjust your data’s layout and colors.
- Change the size of your chart’s legend and axis labels.
How do you label a graph?
The proper form for a graph title is “y-axis variable vs. x-axis variable.” For example, if you were comparing the the amount of fertilizer to how much a plant grew, the amount of fertilizer would be the independent, or x-axis variable and the growth would be the dependent, or y-axis variable.
Is graphing algebra or geometry?
One way that algebra and geometry can be related is through the use of equations in graphs. We can plot a set of points (x, y) according to an equation (for example, the line graph on the left!) to form a graph. That’s one way that algebra is related to geometry.
How does a column graph look like?
A column graph, which is one type of a bar graph, uses vertical bars to display data. Column graphs have four parts: First there’s the title, which explains what information the graph is showing. Labels are displayed on each axis (both x and y) to tell us what each side is representing.
What is needed for a line graph?
Constructing a Line Graph
Line graphs consist of two axes: x-axis (horizontal) and y-axis (vertical). Each axis represents a different data type, and the points at which they intersect is (0,0). The x-axis is the independent axis because its values are not dependent on anything measured.
How does line graph look like?
A line graph shows how a value changes, usually over time. Most line graphs look like a jagged line going across the page. How high the line is above a time marked on the axis tells you how high the value is. A dieter may use a line graph to track how their weight fluctuates as time goes by.
What is a good question for a line graph?
Understanding a Line Graph
| QUESTION | ANSWER | |
|---|---|---|
| 2. | What is the range of values on the horizontal scale? | 2001 to 2007 |
| 3. | What is the range of values on the vertical scale? | 0 to 25,000 |
| 4. | How many points are in the graph? | 7 |

What do you look for in a graph?
In a picture graph, look for the line with the highest amount of pictures. For a bar graph, look for the highest bar. For a line graph and a scatter plot, look at the slope of the line. If the line is pointing to the upper right corner, then the slope is positive.
Which is easy to interpret table or a graph?
Tables, with their rows and columns of data, interact primarily with our verbal system.Tables are also handy when you have many different units of measure, which can be difficult to pull off in an easy to read manner in a graph. Graphs, on the other hand, interact with our visual system.
