Answer:
#6:
A: 
Step-by-step explanation:
Points: (3, -5) and (-7, -1)
Slope Formula: 



Answer: The answer would be 8.
Step-by-step explanation: I'm going to assume you mean 7 8/13 is a mixed fraction. So you multiply the denominator, 13, multiply 7 to that, then add 8 to it and the denominator would be the same as before. That should give you 99/13. When you divide, you get around 7.6, rounding closest to 8.
Replace n with 2 in the bottom equation.
h(2) = h(2 - 1) + 2
h(2) = h(1) + 2
We are given that h(1) is -2. See it?
So, h(2) = -2 + 2, which is 0.
Answer: h(2) = 0.
Got it?
A relation only
Because it is not a parabola
