The graph shows the function () = 4 + 21 and () = -(1/2)^x+4+6
what is the solution?

The line y = x + passes through (−3, 7) and is parallel to y = 4x − 1.

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)
