Question

x 1 2 3 4 5
y -6 -3 0 3 6
what is the slope for this table?
options: -3, 3, -6, 6

Explanation:

Step1: Recall slope formula

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

Step2: Pick two coordinate pairs

Choose $(x_1,y_1)=(1,-6)$ and $(x_2,y_2)=(2,-3)$

Step3: Substitute into formula

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

Step4: Simplify the expression

$m = 3$

Answer:

3
