Question

a linear relationship is given in the table.

x	y
4	5
0	1
-2	-1

what is the slope of the relationship?

• 3
• 2
• 1
• -1

Explanation:

Step1: Recall slope formula

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

Step2: Pick two table points

Use $(x_1,y_1)=(6,7)$ and $(x_2,y_2)=(4,5)$

Step3: Substitute into slope formula

$m = \frac{5 - 7}{4 - 6} = \frac{-2}{-2}$

Step4: Simplify the expression

$m = 1$

Answer:

1
