Answer:
Step-by-step explanation:
So, we are given:
First, we should immediately rule out 0 as an answer. This is because the if 
, the equation would be undefined.
Now, cross multiply.
Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).
We didn't run into any possibilities for extraneous solutions.

Answer:
(a): 26.1
(b): 27.9
Please see below for the steps.
Step-by-step explanation:
(a):
Use points (0,0) and (3, 78.3)
Use slope formula. The slope formula is also used to find average rate of change (just so you know).
y2-y1/x2-x1
78.3-0/3-0=78.3/3=26.1
Answer for (a) is 26.1
(b):
Use points (4, 147.6) and (9, 287.1)
Use slope formula.
y2-y1/x2-x1
287.1-147.6/9-4=139.5/5=27.9
The answer for (b) is 27.9
Hope this helps!

Answer:
(-3.5 8.5)
Step-by-step explanation:
Midpoint Formula: (
, 
)
What I did: -10 + 3 = 7, 7 / 2 = 3.5 x = 3.5 | 9 + 8 = 17, 17 / 2 = 8.5
Midpoint = (-3.5, 8.5)
