Question

X – y = 3 (line a)

x + y = 3 (line b)


(0, –3)


(0, 3)


(–3, 0)


(3, 0)

Answer 1

Answer. You must first put the equation into slope-intercept form (y = mx + b). To do this, subtract x from both sides to isolate y. Then, since y will be negative, divide each side by -1, resulting in y = x - 3.
