Question

find the slope of the line that goes through (2,8) and (5,13)

Answer 1

slope = (y2-y1)/(x2-x1)

         = (13-8)/ (5-2)

        = 5/3

The slope is 5/3

Answer 2

The slope of a line that consists of the two points is found through the equation (y_{2}-y_{1})/(x_{2}-x_{1})

(13 - 8)/(5 - 2) = x

(5)/(3) = 1.66666666666..............    or 1.67
