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

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 2

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).
