Step 1. Pick a value for x. It can be anything you like, but 0, 1, or some other small integer usually works well and makes the arithmetic easier.
Step 2. Substitute that value in place of x in your equation. Do the arithmetic and determine the value of y that results.
Step 3. Take the value of x that you selected for step 1 and the value of y that you calculated in step 2 and form an ordered pair (x,y).
Step 4. Plot the ordered pair from Step 3 on your graph. Remember that the x value is the distance right or left along the horizontal axis and the y value is the distance up or down along the vertical axis.
Step 5. Repeat steps 1 through 4 with a different value for x. Then repeat 1 through 4 two more times. Make sure that you choose two positive values for x and two negative values for x.
Step 6. Draw a line across your graph that passes through the two points that you plotted that have positive x-coordinates. Draw a line across your graph that passes through the two points that you plotted that have negative x-coordinates. The two lines should meet and form an angle at the y-axis, specifically at the point (0,4) for this particular problem.
