Find the slope of the line that passes through (2, 4) and (–7, 8)

Question

A.-4/9

B.-4/5

C.5/4

D.-9/4

Answer 1

slope of line between two points (x1,y1) and (x2,y2) = (y2-y1)/(x2-x1)

here (x1,y1) = (2,4)

(x2,y2) = (-7,8)

using formula, slope = (8-4)/(-7-2) = -4/9 (A)

Answer 2

slope M = (8-4)/(-7 -2) = 4/ -9 = -4/9

option A
