m = -8 - -4
_______ = -4/-10? and then im lost but what i have is kind of experimental

-17 - -7

m = -8 - -4
_______ = -4/-10 = -2/-5?

-17 - -7
(y - -8) = -2/-5 (x - -17)
y - -8 = 10x - -170
+8 +8
y = 10x + -178
-10 -10
-(-10x + y = 82)
answer? 10x + -y = -82???
the steps are missing i know but i was trying by looking off what i did in class with the teachers help but it didnt work very well so please can anyone help me!?!?
