for a linear function m= rise/ run

if given 2 points on the graph m= (y2-y1)/(x2-x1)

remember to simplify (lowest terms)!

the 2 behind the x and the y is are not exponents! They mean the range in the second bracket:

ex. (5,6)<--- 6= x2 5= x1

(7,8) <--- 8= y2 7=y1

How do you find slope if the points aren't given?

the slope is the 'm' in y=mx+b so even if the points aren't given, if there is an equation, then you can find the slope. for example, if you have an equation like this: y=2x+5 the slope is 2 and the y-intercept is 5.

Use: (y2 -y1)/(x2 -x1) to find the slope. Use: y -y1 = m(x -x1) to find the slope intercept equation whereas m is the slope.


How do you find the height of a slope given two points?

To find the slope (steepness, not height) of a line when given two points, do the following: Slope = (y2-y1)/(x2-x1), where (x1, y1) is one point, and (x2,y2) is the second point.
