Use a graphing tool to solve the system. {13x+6y=−30x−2y=−4 which ordered pair is the best estimate for the solution to the system?

13x+6y = -30................y = -5 -13x/6
x−2y=−4...................... y = x/2 +2 

If we graph both lines we can get the solution of the system (point of intersection)

The best estimate is (x,y) = (-2.625, 0.688)
