Solve the following system by graphing.

x - y = 4

x + y = 2

What is the solution of the system?

A) (3, - 1)

B) (3, 1)

C) (-1, 3)

A

Step-by-step explanation:

3 - - 1 = 4

3 + - 1 = 2

A. (3,-1)

Step-by-step explanation:

x - y = 4

x + y = 2

2x = 6

x = 3

3 - y = 4

y = - 1

Draw two straight lines passing through:

1) (0,-4) and (4,0)

2) (0,2) and (2,0)

You'll see that the two intersect at: (3,-1)
