Given the following graph where are the solutions located?

i and iii

ii only

i only

ii and iii

I and II

When a graph has a solid line, solutions lie ON that line, whereas if it was a dotted line, solutions lie only on the shaded side of that line, not the line itself.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
