Just remember the rule when you add two negatives together

Answer 3

Why do you use the second point as (x1,y,2) instead of the first ;) Doesn't matter, just curious.

Answer 4

I mean (x,1,y1)

Answer 5

Yes, I have learned it y2-y1 / x2-x1

Answer 6

(x1, x2), (y1), y2)

Answer 10

either way ...

Answer 11

-8 - (-2)

Answer 12

Answer 14

-8 - -2 = -6...and ohhh...
i did -5 - -15 lolz

Answer 15

yes, and that's where you got confused, because the 15 is positive in the coordinate.

Answer 16

it is easy to make an error when you are doing the subtraction

Answer 17

but I find if you write it out with the - in () then you can just change it a plus

Answer 18

it is (-2,15) , NOT (-2,-15)

Answer 19

Yeah i saw that lolz...
