Hope it helps :)

-4

7

Step-by-step explanation:

You have to use the formula y2-y1

                                                x2-x1

So -4-4

     8--6

-4-4= -8

8--6= 14 (two negative signs become a positive sign)

You have -8 over 14

If you simplify it's -4/7 or -4

                                         7
