-8,-2
Step-by-step explanation:
2/5 at the top nd bottom, but 0/5 on the sides. So 2/5 + 0/5= 1/5
let's recall that an inverse function has the same pair of coordinates as the original function, but backwards, or namely the inverse's range is the original's domain.

Y= -2/3 +6 bc...
(-3,8)
y=mx+b
8= -2/3(-3) +b
8=2+b
-2 -2
6=b
