On a coordinate plane, a line with negative slope goes through (0, 4) and (4, 0). The graph is shown for the equation y = –x + 4. Which equation, when graphed with the given equation, will form a system that has an infinite number of solutions? y = negative 4 (x + 1) y = negative (x + 4) y = negative one-half (2 x minus 8) y = x + negative 4
