Question

what is the slope of this line? (with a coordinate grid showing a line passing through (0,0), (2,2), (4,4) etc.)

Explanation:

Step1: Recall slope formula

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

Step2: Identify points

Use $(x_1,y_1)=(2,2)$ and $(x_2,y_2)=(4,4)$

Step3: Substitute values into formula

$m = \frac{4 - 2}{4 - 2}$

Step4: Calculate the slope

$m = \frac{2}{2} = 1$
