Which description best describes the solution to the following system of equations?

y = - one halfx + 9

y = x + 7

Lines y = - one halfx + 9 and y = x + 7 intersect the x-axis.

Lines y = - one halfx + 9 and y = x + 7 intersect the y-axis.

Line y = - one halfx + 9 intersects the origin.

Line y = - one halfx + 9 intersects line y = x + 7.

    Y=-x/2+9

    y=x+7

    If we solve this system of equations, we can find the solution to the following system of equation.

    we can solve this system of equation by equalization method.

    -x/2+9=x+7

    lowest common multiplo=2

    -x+18=2x+14

    -3x=-4

    x=-4/-3=4/3

    y=x+7=4/3 + 7 = (4+7*3) / 3=25/3

    The solution is (4/3, 25/.3)

    answer: Line y=-x/2+9 intersects line y = x+7
