Use the slope formula: (m = frac{y_2 – y_1}{x_2 – x_1})
Identify two points on the line: ((x_1, y_1)) and ((x_2, y_2))
Subtract the y-values to find the rise
Subtract the x-values to find the run
Divide the rise by the run
Simplify the fraction if possible
If the line is horizontal, the slope is 0
If the line is vertical, the slope is undefined
If the equation is in slope-intercept form (y = mx + b), the slope is (m)
If the equation is in standard form (Ax + By = C), rewrite it as (y = mx + b) to find the slope
