Hey those are linear functions, gotta find Y or X and draw on two axis X/Y. in first y = 4/9x + 1/9. in second y = X/2 - 2.
a=16 b=28
this is because you can use the ratio to make the equation 4x+7x=44 which turns to 11x=44 and that simplifies to x=4 so to get a you multiply 4 and 4 or a=4*4 and to get b you multiply 7 and 4 or b=7*4 so a=16 and b=28
