You can put this solution on YOUR website!
There are several ways to do it, and I don't know how you would choose to proceed, but if it were me, I would use the following procedure:
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.
Step 6. Draw a line across your graph that passes through the two points that you plotted.
Then again that is just me, and since we clearly view the world differently. For example I, in stark constrast to you, make it a rather rigorous habit to capitalize the first letter of the first word of my sentences and also to capitalize the first person singular pronoun.
