What is the rule fo this????? PLease help! :]

SKETCH A GRAPH!
find equation of line from (0,0) to (2,2)
slope = m = 2/2 = 1
0 = 1 (0 ) + b
b = 0
so
y = x
is the equation of the line
Try the other points :) 
I'm sorry. I don't have a clue what you're talking about.

if x = 513
then y = 513 
I still don't get it. I'm sorry, but we just started talking about this.

OHHHHH!!!! I know! It's x= y x [1]

Whew !
