Question

Which is the slope of a line through the points (-1, 2) and (5, 8)?

Answer 1

Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (5, 8 )

m = $\frac{8-2}{5+1}$ = $\frac{6}{6}$ = 1 → A
