You have the right answer, but the equation is flopped... Needs to be

Answer 14

it doesnt matter

Answer 15

@CShrix it turns out that it doesn't matter if you do y2-y1 or y1-y2. The only thing that matters is if you keep the order the same

If you did y2-y1, then you have to do x2-x1
If you did y1-y2, then you have to do x1-x2
