What are the two methods to find slope?
Terms in this set (8)
- Slope. y2 – y1 / x2 – x1 = slope.
- Slope Intercept form. y = mx + b.
- Point slope form. y – y1 = m ( x – x1)
- Standard Form. Ax + By = C.
- x – axis. The horizontal line on a graph.
- y – axis. The vertical line on a graph.
- X – intercept. The point on a line that intercepts on the x axis.
- Y – intercept.
How do you find slope in slope-intercept form?
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept. In our equation, y = 6x + 2, we see that the slope of the line is 6.
How do you find the slope intercept?
Using the “slope-intercept” form of the line’s equation (y = mx + b), you solve for b (which is the y-intercept you’re looking for). Substitute the known slope for m, and substitute the known point’s coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.
How do you find slope in standard form?
The standard form of a linear equation is Ax + By = C. When we want to find the slope of the line represented by this equation, we have two options. We can put the equation in slope-intercept form and identify the slope that way, or we can use the formula m = -A/B.
How many ways are there to find slope?
Three ways to find the slope of a line:
- You may have two points (x1,y1) and (x2,y2) (often one or both of these points may be intercepts of the x and/or y axes).
- You may have a linear equation that is either in the form or can be manipulated into the form.
What is the slope of y =- 5 4xy?
Pre-Algebra Examples
Using the slope-intercept form, the slope is −4 .
What is the slope in Y MX B?
We rewrite the standard form of the equation of the line to the slope-intercept form y = mx + b. Comparing the final equation with y = mx + b, we obtain the slope of the equation is m = -2/3 and the y-intercept of the equation is, b = 2 or (0,2).
How do you find the slope of 5 points?
