Which one is it? ? because i really i dont under

Hello from MrBillDoesMath!

Choice D.

Discussion:

Substitute the values (5,7), (8,13) into the equations and see what we get..

A.  (5,7). Does 3(5) -7 = 8. Yes  

    (8,13). Does 3(8)-13 = 8 ? No. Points  (8.13) does NOT lie on the line

B.  (5.7). Does 7 = 5 + 2. Yes.

    (8,13). Does 13 = 8 +2 ? No. Points  (8.13) does NOT lie on the line

C.  (5,7). Does 7 -5 = 5 ? . No

    (8,13). Does 13-8 = 5? Yes

D.  (5.7). Does 7 = 2(5) - 3  ?  Yes.

    (8,13). Does 13 = 2(8) - 3?  Yes

Only choice D has both points lying on the line.
