To write: The equation that relate the profit and graph the function and check for intercepts.

Answer to Problem 15CT
Y - Intercept is
X - Intercept is
Explanation of Solution
Given information:
Number of pets to groom =
Profit =
Amount spent on supplies =
Amount spent to charge on grooming each pet =
Graph:
Assuming the value of x to find
Interpretation:
Profit is directly proportional to the difference between amount spent to charge on grooming each pet and the amount spend on supplies.
Here
Therefore the rate of change is
And the spend on supplies =
Hence the profit can be related as
The y-intercept of the straight line is the point where the line crosses the y axis that is at
Therefore y-intercept is
The x-intercept of the straight line is the point where the line crosses the x axis that is at
Therefore x-intercept is
