Question

What is the slope of line a? 48 POINTS

Answer 1

Answer:

-3

Step-by-step explanation:

$Slope = \frac{Change in Y}{Change in X}$

Take two points

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

Plug in their y and x coordinates

$\frac{-5 - 1}{1-(-1)} =\frac{-6}{2} = -3$

Answer 2

Answer:

1st answer is correct.

Step-by-step 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

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

Let us find it now.

$m = \frac{-2-1}{0-(-1)}\\m = \frac{-3}{1}\\m=-3$
