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

For a system to have no solution, the lines must be parallel but have different y-intercepts. The given equation is y = 8x + 7, with slope 8 and y-intercept 7. Choice B, y = 8x − 7, has the same slope but a different y-intercept, so the lines never intersect.
