Beginner Explanation
Step 1: Write the equation in slope-intercept form $y = mx + b$ if it isn’t already. Step 2: Plot the y-intercept (0, b) on the coordinate plane. Step 3: From that point, use the slope m (rise over run) to find a second point. Step 4: Draw a straight line through the two points.
