y=1/7* x
the first number in the pair is x
The second number is y
When you plug in the x and the y which one  really equals the other?
3=1/7*21
Does the right side equal 3?
3=21/7  Does 21/7 equal 3? If so you are done
If not keep going until you find one where the left side does equal the right side.
