(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2
