Answer:

D) (1,5)

Step-by-step explanation:

You have to substitute so...

(-1,0):

y = 3x + 2

0 = 3(-1) + 2

0 = -3 +2

0 = -1

(-1,0) is NOT a solution.

(0,3):

y= 3x + 2

3 = 3(0) + 2

3 = 0 +2

3 = 2

(0,3) is NOT a solution.

(1/3,1):

y = 3x + 2

1 = 3(1/3) + 2

1 = 1 + 2

1 = 3

(1/3,1) is NOT a solution.

(1,5):

y = 3x + 2

5 = 3(1) + 2

5 = 3 + 2

5 = 5

(1,5) IS a solution.
