A.6-3 3-(-3)
-3-1 -1-3
B.6-3 3-3
-3-(-1) -1-3

Answer:
Step-by-step explanation:
Answer:
C.
(6 - 3)/(-3 - (-1))
(3 - (-3))/(-1 - 3)= 6/(-4)
Step-by-step explanation:
Slope AC = (y(A) - y(C))/(x(A) - x(C)) = (6 - 3)/(-3 - (-1)) = 3/(-2)
Slope CE = (y(C) - y(E))/(x(C) - x(E)) = (3 - (-3))/(-1 - 3)= 6/(-4) = 3/(- 2)

Answer: Y-1=-1/8(X-3)
Step-by-step explanation:
Point slope form is Y-y1=m(x-x1)
the slope here is 2-1/-5-3 = 1-/8
so its Y-1=-1/8(X-3)
