The graph for the equation y = 2 x minus 2 is shown below. On a coordinate plane, a line goes through points (0, negative 2) and (1, 0).

If another equation is graphed so that the system has one solution, which equation could that be?

y = 2 (x + 1)

y = 2 (x minus 1)

y = 2 (x minus 2)

y = negative 2 (x + 1)
