On the x column, you would write 1, 2, 3, 4, and so on. Then, in the y box, you plug in that number into the equation. Write your answer in the y column.
For example, if x = 1, then 1^2 + 2 - 8 = - 5.
If x = 1, y= -5
Add 1 to both sides of the equation to get 4x = 4.
Divide both sides by 4 and <em>x = 1</em>.
