Answer:

B

Explanation:

Calculate the slope m using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (- 8, 1) and (x₂, y₂ ) = (- 3, - 4)

m =
(-4-1)/(-3+8) =
(-5)/(5) = - 1 → B

Answer:

B. -1

Explanation:

Use the following equation:

slope
m =
(y_2 - y_1)/(x_2 - x_1)

Let:


(x_1, y_1) = (-3 , -4)\\(x_2, y_2) = (-8 , 1)

Plug in the corresponding numbers to the corresponding variables. Simplify:


m = ((1) - (-4))/(-8 - (-3)) = (1 + 4)/(-8 + 3) = (5)/(-5) = -1

Slope (
m)
= -1, or (B).
