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

To complete your spring schedule, you must add calculus and physics. at 9: 30, there are three calculus sections and two physics sections; while at 11: 30, there are two calculus sections and three physics sections. how many ways can you complete your schedule if your only open periods are 9: 30 and 11: 30?
