Question

Find the slope of the line that contains (-8, 2) and (7,-4).a. - 2/5 b. -5/2 c. 0 d. undefined

Answer 1

The formula for determining slope is expressed as

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

From the information given,

x1 = - 8

x2 = 7

y1 = 2,

y2 = - 4

Therefore,

Slope = (7 - - 8)/(- 4 - 2) = 15/- 6

Slope = 5/-2 = - 5/2

The correct option is b
