Solve the system of equations by graphing.

OpenStudy (anonymous):

\[x-3y=9 \]

OpenStudy (anonymous):

\[x+3y=-3\]

OpenStudy (anonymous):

those are the 2 equations

OpenStudy (anonymous):

x-3y=9 x+3y=-3 2x = 6 x=3 y=-2

OpenStudy (anonymous):

do you just graph those 2 points after that

OpenStudy (anonymous):

Well, that is a bit more involved. You should graph the two lines and show that the intersection of the two lines is x=3, y=-2.
