1. y=f(x)=170x-4 is a function with variable x representing a year.
2. Let's consider the difference between 2 consecutive years, say year 3 and year 4
f(3)=170*3-4
f(4)=170*4-4
we expect f(3)-f(4) to be 4 since after 4 years, the water will be 4 feet less than after 3 years.
check: f(3)-f(4)=(170*3-4)-(170*4-4)=170*3-4-170*4+4=170*3-170*4=170*(3-4)=170*(-1)=-170
The distance is determined by the y-intercept. The y-intercept for one line is 2 and the other is 4 so the distance from 2 to 4 is 2.

Answer:
<h2><u><em>
8.17</em></u></h2>
Step-by-step explanation:
- <em>What is the number between 8.1 and 8.24?</em>
<em></em>
<em>Add the numbers and divide by 2 and you will find the average</em>
(8.1 + 8.24) : 2 =
8.17
8.17 is exactly half way between them.
