Question

Find the slope of the line that goes through the points (15,5) and (2,11).

Answer 1

(15,5) and (2,11) have a line through them with slope =

difference in y coordinates divided by difference in x coordinates

= (11-5)/(2-15) = -6/13

Answer 2

Slope is the change in y vs. the change in x (rise/run)

(y₂ - y₁)(x₂ - x₁) = (11 - 5)/(2 - 15) = 6/-13 = - 6/13
