Answer:
If you want a fraction it would be -1/4 if you want a decimal it would be -0.25
Explanation:
You have to take your X2- your X1 and you take your Y2- your Y1
Then you divide Y/X
So Your X2 would be 6 and X1 would be -6 and that would become a positive 12.
And your Y2 would be 2 and your Y1 would be 5 which would give you -3 when you subtract.
Then divide it 12/-3 which would give you -1/4 since you have to flip your fraction.
