Write the equation in slope-intercept form, y = mx + b, if possible
Identify the y-intercept, b
Plot the y-intercept on the graph
Identify the slope, m, as rise over run
Use the slope from the y-intercept to find a second point
Plot the second point
Draw a straight line through the points
Extend the line in both directions
Check that all points satisfy the equation
Label the line if needed
