Question

What is the slope of the line that passes through the points (7, -2 ) and ( -1, -5)

A. 3/8

B. -3/8

C. 1/2

D. 0

E. 8/3

Answer 1

A

to calculate the slope m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, - 2 ) and (x₂, y₂ ) = (- 1, - 5 )

m =
`(-5+2)/(-1-7)` =
`(-3)/(-8)` =
`(3)/(8)` → A
