(4,-1). 4x+3y=13. You do 4(4)+3(-1)=13. hope that helps.

We can substitute each and check if it gives us the answer 13

1st one:
4(1)+3(6) = 13
4 + 18 = 13
22 ≠ 13
It does not satisfy the equation!

therefore, The last one is the answer after checking them all.

4(4) + 3(-1) = 13
16 - 3 = 13
13 = 13

(4, -1)
