−15x−5y=45
−2x+6y=6
graph the system of equations.
(picture)
for the graph you have to point the points
what is the solution?
x=__
y=__

You can reword the two equations as:
-5x-y=15 (Divide original value by 3)-2x+6y=6
Then use elimination to find x:
-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)-2x+6y=6
You're left with:
-32x=96. Which can then be solved to find x which is -3.
Then plug back in 
-2x+6y=6
Now to: -2(-3)+6y=6.
Which reduces to 6+6y=6. So y=0.

To graph them, just reword the equations (yes once again) so that y is in front.
y=-5x-15 and y=(1/3)x+1
