Slope-Intercept Form: To graph an equation in slope-intercept form: 1. Must be in the form of y = mx + b. Identify m and b. 2. Plot the y-intercept (0, b). 3. Starting at the y-intercept, find another point on the line using the slope. 4. Draw the line through (0, b) and the point located using the slope.
