This is a very simple and easy problem. I'm not sure why you need someone else to solve it, but I hope this helps
a. Linear equation:
Let x be amount of movies rented
$8 + ($2.50 * x)
b.
$8 + ($2.50 * 10)
= $8 + $25.0
= $33
Answer:
A
Step-by-step explanation:
Doesn’t pass the linear line test. 2 y values for 1 x value
To get the distance between
and
, we subtract
from 
That is,

We change the mixed number to improper fraction now to get,

This is the same as,

We collect LCM to be 4

This gives us,


Convert back to mixed number to get,

Therefore the distance between the two numbers is 
Note that the other way round will result in negative value. That is subtracting 6 from
will give 
But since this is distance we find the absolute value and get the same result.
