What is 9 plus 3 plus 7 plus 2 plus 6

The answer is 27, mate.

You did not list the choices. however, if you plug in a choice you can figure this out. if the coices were (1,2) and (1/3,1) we could plug in one at a time.

y = 2x + 1/3
2 = 2 (1) + 1/3
2 = 2 1/3
this is not right so it is not an answer.

check other one
y = 2x + 1/3
1 = 2 (1/3) + 1/3
1 = 2/3 + 1/3
1 = 1
this would be a solution since true. hope this helps
