Question

What is the slope of line a? 48 POINTS

Answer 1

-3

Explanation:

`Slope = (Change in Y)/(Change in X)`

Take two points

(1, -5) and (-1, 1)

Plug in their y and x coordinates

`(-5 - 1)/(1-(-1)) =(-6)/(2) = -3`

Answer 2

1st answer is correct.

Explanation:

First, let us take two coordinates of the line.

( 0 , -2 ) ⇒ ( x₁ , y₁ )

( -1 , 1 ) ⇒ ( x₂ , y₂ )

We have to use the below formula to find the slope of the line.

Slope = m

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

Let us find it now.

`m = (-2-1)/(0-(-1))\\m = (-3)/(1)\\m=-3`
