The two lines, x and y, are graphed below:

determine the solution and the reasoning that justifies the solution to the systems of equations.
answer chocies:
a.(2, 7), because this point is true for both the equations
b.(4, −6), because this point lies only on one of the two lines
c.(4, −6), because this point makes both the equations true
d.(2, 7), because the lines intersect the x-axis at these points
