Question

what is the lines slope?

Explanation:

Step1: Pick two points on the line

Choose $(0, -1)$ and $(2, 1)$ (clear grid intersections)

Step2: Apply slope formula

Slope $m = \frac{y_2 - y_1}{x_2 - x_1}$
$$m = \frac{1 - (-1)}{2 - 0} = \frac{2}{2}$$

Step3: Simplify the fraction

Reduce the fraction to lowest terms
$$m = 1$$
