Question

find the slope of each line.
13)
graph of a line on a coordinate plane with grid lines, including two marked points on the line

Explanation:

Step1: Identify two points on the line

The line passes through $(-2, 1)$ and $(-1, 3)$.

Step2: Apply slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$
Substitute points: $m = \frac{3 - 1}{-1 - (-2)}$

Step3: Calculate the slope

Simplify numerator and denominator: $m = \frac{2}{1} = 2$
