Question

Use the graph to state the solution for the system.


x – y = 3 (line a)

x + y = 3 (line b)



(–3, 0)


(3, 0)

(0, –3)


(0, 3)

Answer 1

My answer is B

Answer 2

very good. The solution is the intersection point between the two (diagonal) lines

Answer 3

ok thanks

Answer 4

it is the point that is on both equations at the same time

Answer 5

here's how you algebraically check


x-y = 3
3 - 0 = 3 ... replace x with 3, y with 0
3 = 3 .... equation is true


x+y = 3
3+0 = 3 ... replace x with 3, y with 0
3 = 3 .... equation is true


since both equations are true when (x,y) = (3,0), this algebraically confirms the solution
