Question

Find the slope of a line that goes through (-8, 1) and (-3, -4)

A. -11/3
B. -1
C. 5/5
D. 3/5

Answer 1

Answer:

B

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

m = $\frac{-4-1}{-3+8}$ = $\frac{-5}{5}$ = - 1 → B

Answer 2

Answer:

B. -1

Step-by-step explanation:

Use the following equation:

slope $m =$ $\frac{y_2 - y_1}{x_2 - x_1}$

Let:

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

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

$m = \frac{(1) - (-4)}{-8 - (-3)} = \frac{1 + 4}{-8 + 3} = \frac{5}{-5} = -1$

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