Question 50314
x+y=2 [Rewrite as y=mx+b by solving for y]
y=-x+2
Plug-in different values for the x's and solve for the y's.  
Graph the results.

3x=2y=9 ?????[Rewrite as y=mx+b by solving for y] 
If the equation is suppose to be:
3x-2y=9, than y = 3/2x-9/2
.
If the equation is suppose to be:
3x+2y =9, than y = -3/2x + 9/2
.
Plug-in different values for the x's and solve for the y's.  
Graph the results.
