A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be

O 2y = 16x + 14

O y = 8x - 7

O y=-8x + 7

O 2y = - 16x - 14

    y=8x-7

    Step-by-step explanation:

    Two equations on the same plane are not going to have a solution if they are parallel.

    Parallel lines have the same slope and a different y-intercept.

    Slope-intercept form of a line is y=mx+b where m tells us the slope and b tells us the y-intercept.

    The slope and y-intercept of y=8x+7 is 8 and 7 respectively.

    So I already see one line with the same slope and that is y=8x-7. Guess what? It has a different-intercept then y=8x+7. It's y-intercept is - 7.
