Question

x | y
-3 | 5
-2 | 2
-1 | -1
0 | -4
1 | -7
what is the slope?
options: -4, -1/3, 5, -3

Explanation:

Step1: Recall slope formula

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

Step2: Pick two coordinate pairs

Choose $(x_1,y_1)=(-3,5)$ and $(x_2,y_2)=(-2,2)$

Step3: Substitute into formula

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

Step4: Simplify the expression

$m = -3$

Answer:

-3
