Sylvie solved this system of equations. y = 5x + 2, y = 8 – x 8 – x = 5x + 2 8 = 6x + 2 6 = 6x x = 1 8 – 1 = 5(1) + 2 7 = 7 there are infinite solutions to this system. when sylvie verified the solution on a graph, the lines intersected at one point. what was her error?

she forgot to put both equations in slope-intercept form.
she made an arithmetic mistake in the last step.
she found the incorrect value of x.
she did not substitute the value of x into one of the original equations to find y.
