So far, you've been graphing lines and parabolas.  This is just the tip of the iceberg!  I'm sure you'll be thrilled to know that there are other cool graphs to work with!  (I know I am...  but, then again, I'm a geek.)

First, here's a special line guy that you've probably seen before...  I call him  45 degreesLine Guy:

y = x

graph of y = x ... points on the line include ( -2 , -2 ) , ( -1 , -1 ) , ( 1 , 1 ) , and ( 3 , 3 )

And you probably already love Standard Parabola Guy:

y = x^2

graph of y = x^2 ... points on it include ( -2 , 4 ) , ( -1 , 1 ) , ( 0 , 0 ) , ( 1 , 1 ) , and ( 2 , 4 )
