Question

What is the slope of the line that goes through the points (1,-5) and (4,1)? A. B. C. D.

Answer 1

2

Explanation:

The formula of a slope:

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

We have two points (1, -5) and (4, 1).

Substitute:

`m=(1-(-5))/(4-1)=(1+5)/(3)=(6)/(3)=2`

Answer 2

slope = 2

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, - 5) and (x₂, y₂ ) = (4, 1)

m =
`(1+5)/(4-1)` =
`(6)/(3)` = 2
