Solve the system of equations by graphing. Then classify the system.x+y=8x-y=-2

• Math -

I assume you have

x+y = -2
8x - y = -2

solve by graphing??
(perhaps to show the concept)
Just add them
9x = -4
x = -4/9

then -4/9+y=-2
y = -14/9

(I doubt if you could have obtained that exact value by looking at a graph)
