How do you find the slope of a line between two points?

M= Slope

M=(Y1-Y2)/(X1-X2)

If you have two points on a graph, say (3,7) and (2,5), then the "Y" variable would be the second number in each point and the "X" variable is the first number.

For example:

M= (7-5)/(3-2)

M=2/1

M=2, so the slope of a line between points (3,7) and (2,5) is 2.

Note you can pick either point to be point "1" or "2":

(5-7)/(2-3) = (-2)/(-1) = 2, as well.
