We talked about how to use this formula to find the slope between any 2 points.

​

You should be able to memorize this for the test! ​

slope of a graph

Remember, "m" is the same as the constant or the unit rate. In this equation, it is the "slope".

The y-intercept determines where the line starts on ​coordinate plane and if it is a proportional relationship or not.
