The y-axis is like a vertical ruler. It shows you where an object on a Cartesian plane, a two-dimensional mathematical graph, is in the y (vertical) direction. It is also the starting, or zero, point for measuring how far a point is to the right or left (horizontally) on a graph.

What does the y value represent on a graph?
The y value of a point where a vertical line intersects a graph represents an output for that input x value.
What does the axis represent on a graph?
X-axis is the axis of the cartesian plane which represents the horizontal axis. The graph points plotted on the x-axis are from left to right. Y-axis is the axis of the cartesian plane which represents the vertical axis. The graph points plotted on the y-axis are from top to bottom.
What does y-axis mean in science terms?
Y-axis (noun, “Why AXE-iss”)
A vertical line on a graph. It can be located to the right or left, or even in the middle. Scientists label the y-axis with whatever they are measuring. Perhaps it is time, or a population, or grams of a substance.
What is the point where the curve crosses the y-axis called?
In the equation y = a + b x, the constant labeled “a” is called the y-intercept. The y-intercept is the point at which the line crosses the y-axis.
What does the y-axis represent on a bar graph?
In most bar graphs, like the one above, the y-axis runs vertically (us and down). Sometimes bar graphs are made so that the bars are sideways like in the graph to the left. Then the y-axis is horizontal (flat). Typically, the y-axis has numbers for the amount of stuff being measured.
What is an axis used for?
An axis is the reference line that is used to measure coordinates on graphs and grids. There are typically two axis lines (axes) on a graph; the y-axis and the x-axis.
What is a reflection over the y-axis?
Reflect over the y-axis: When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
What is the value of y-axis?
The point where the X and Y-axis intersect is known as the origin and is used as the reference point for the plane. The X-axis is also known as abscissa. The Y-axis is also known as ordinate.
X and Y-Axis Definition and Difference.
| X-Axis | Y-Axis |
|---|---|
| Known as abscissa | Known as ordinate |
| Referred to (x,y) | Referred to (x,y) |
What dimension does the y-axis represent?
A three-dimensional structure. The x-axis and y-axis represent the first two dimensions; the z-axis, the third dimension. In a graphic image, the x and y denote width and height; the z denotes depth.
What is the other term for the y-coordinate of a point?
ordinate
Another name for the y-coordinate is the ordinate. Note: The x-coordinate or abscissa represents the directed distance of the point from the y-axis.
Which type of data is presented on the y-axis?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line).
Where is the y-axis on a graph?
A y-axis is the line on a graph that is drawn from bottom to top. This axis is parallel to which coordinates are measured. The numbers placed on the y-axis are called y-coordinates. Ordered pairs are written in parentheses, with the x-coordinate written first, followed by the y-coordinate: (x, y).
What do the values on the horizontal axis represent?
horizontal axis | Business English
the line of figures or coordinates that are arranged from left to right along the bottom of a graph or map: The vertical axis represents value; the horizontal axis represents time.
What is Axis in simple words?
The definition of an axis is a real or imaginary line on which something rotates, or a straight line around which things are evenly arranged. An example of axis is an imaginary line running through the earth on which the earth rotates.A main line of motion, development, etc.
What does axis mean in history?
the Axis the alliance of Nazi Germany, Fascist Italy, and Japan, established in 1936 and lasting until their defeat in World War II.
An axis is an invisible line about which an object rotates, or spins. 5 – 12+
What does it mean to reflect over the line Y 2?
the x-values of the mirror image will stay the same. look at the y-values. the y-values must be the same number of units below the line y=2 as above the line y=2. for example, if a y-value is 2 units above the line y=2, the mirror image of that y-value must be 2 units below the line y=2.
How do you mirror a function about the y-axis?
To flip or reflect (horizontally) about the vertical y-axis, replace y = f(x) with y = f(-x).
What does XYZ mean in position?
When performing precision shaft alignment on horizontal rotating machinery, the Z axis refers to the rotational axis or rotational centerlines. The Y axis refers to vertical position (perpendicular to the base) and the X axis refers to the horizontal position (parallel to the base).
How do you read XYZ coordinates?
Cartesian coordinates of the plane
The first number x is called the x-coordinate (or x-component), as it is the signed distance from the origin in the direction along the x-axis. The x-coordinate specifies the distance to the right (if x is positive) or to the left (if x is negative) of the y-axis.
