Question 744724:  Graph the equation x+3=y by finding three points on the line 
 Answer by Cromlix(4381)      (Show Source): 
You can  put this solution on YOUR website! Substitute x values into your equation to obtain the y coordinate. 
x= -2  => -2 + 3 = 1 :     y = 1 
x = 0  => 0  + 3 = 3 :    y = 3 
x = 2  =>  2 + 3 = 5 :    y = 5
 
So your 3 points on this line are: 
 (-2, 1) (0, 3) and (2, 5)
