How to find a slope

Question

Find the slope of the line that goes through the given points.

(- 1, - 10) and (2, - 4)

Answer 1

(-1, -10) and (2, -4) have a line through them with slope = (-4+10)/(2+1) = 6/3 = 2

slope = rise over run = change in y coordinates divided by change in x coordinates.

as y increases 1, y increases by 2
