How do you find the rise over run?

Answer 1

Rise over run, or slope, is found by dividing the difference of both outputs by the difference of both inputs. The equation would look something like this (Y2-Y1)/(X2-X1) Basically, your Y point values are always subtracted in the numerator and divided by you X point values which are subtracted in the denominator. The order in which you subtract DOES matter. If you subtract Y1 from Y2 you must then subtract X1 from X2 and vice versa.
