1. The function of this graph is f(x) = 0.5x + -2
Plug (-2) into the x variables so it looks like:
f(-2) = 0.5 (-2) + -2
Then solve.
Answer: f(-2) = -3
**I'm not as sure about this one, so I might be wrong
2.
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
