Question

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

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 = $\frac{-5+2}{-1-7}$ = $\frac{-3}{-8}$ = $\frac{3}{8}$ → A
