Well, you can actually tell it is D without solving it because it is the only one that has the x value as 3. But just to be sure.
Plug in 3 for x into the equation:
3(3)-y=9 and solve for y
9-y=9 subtract 9 from both sides
-y=0 so y=0
so the value is (3,0)
basically the answer is 2n-1 2n comes from the difference to get from 1 to three and the -1 from 2n to get to 1 you need to minus 1 so you get -1
