Just look up a calculator of that type of work on your phone and it will help I promise
Y= 6 + x
Plug the numbers into the equations, for each ordered pair substitute the first number (2) for x and the second number (8) for y...
Do the same thing with (6, 12) and if the number on each side of the equals sign is the same for both ordered pairs then you have the solution.
Hope that helps!
