Basically all you have to do is plug in numbers for Y and C. the formula is (y,x) so use numbers like (1,3) and as long as it fits in the equation (the equation ends up true. like in this case (1 < 2) which means it worked) you can graph that point.
So for the first one think of it as decimals so it’s easier: 9.20-7.35, subtract and it would be 1.85 so since we use decimals to make it easier it isn’t actually a decimal so it would be 2 hours and 25 minutes. And for the second one you just add 50 minutes to that and you would get 3 hours and 15 minutes.
I think the answer would be 85.1
