Find when x = 0 and when y = 0. Those two points use a ruler and connect them. When y= 0 x = 2; When x = 0 Y = 1

Rewrite the equation as Y=(X2)+1. Find the intercepts. Intercept for Y is 1, X is -2. To find these values substitute 0 for X and Y seperatley. This is actually a great equation for doing this no fractions, square roots, or decimals. Now plug in a few whole number for X. For X=2 Y=2, for X=4 Y=3, for X=6 Y=4. By now you should see a pattern forming. What you could do is graph Y=X/2 first. When you have this graphed add in the +1. You'll end up going up the Y axis by 1. Good luck.

Go to 1 on the y-axis and make a dot. Go up 1, over(right) 2 and make a dot. Go up 1, over(right) 2 and make a dot. Go up 1, over(right) 2 and make a dot. ... See, the 1/2 is the up 1, over 2 thing. - You can also just go down 1 and over(left) 2 for the same thing. Draw a line through the dots and anywhere on that line you can pick where the y is and where the x is and the equation will be equal!
