Answer:
5y+4
Step-by-step explanation:
The slope of the trend line is 0.90 ($900), which represents an increase in <em>salary</em> of $900 for every $1,000 increase in <em>annual tuition cost. (Third Option).</em>
<em><u>Recall:</u></em>
- Slope of a trend line usually depicts a unit rate between two variables.
- The equation of a trend line is usually represented in slope-intercept form as, <em>y = mx + b</em>.
- Where, m is the slope, x and y are the two variables that are changing, while b is the initial value.
Given the equation representing the trend line as, s = 0.90c + 26.4
The slope of the trend line would be 0.90, which is $900.
This means that, there is an increase in <em>salary</em> of $900 for every $1,000 increase in <em>annual tuition cost. (Third Option).</em>

25% decrease because if you multiply 20x.25 you get 5 and you minus the 5 from 20 books and you get 15 books
Answer:
Input variable x: Number of classes he attends.
Output variable y: Monthly cost
Slope: Cost per class, of $2
y-intercept: Membership fee, of $25.
Function: 
Step-by-step explanation:
This situation can be represented by a function is the following format:
In which y is the monthly cost(output), m is the cost per class(slope), x is the number of classes he attends(input) and b is the membership fee(y-intercept).
We have that:
There is a membership fee of $25 per month and a fee of $2 per workout class he attends.
This means that 
. So
7^2x4 = n^8
7^8 = n^8
n = 7
