plot it the way you plot any function! Pick some values of x and calculate y. Then plot the point at (x,y).
The curve will be smooth, but the only poi9nts that make sense in the real world are where x is a divisor of 75.
Your graph should look like this:

Jeff builds model train layouts. He has $75 to spend on packages of miniature landscape items. He receives 6 free packages with each other. The number of packages that Jeff can buy is given by y = 75/x + 6, where x represents the cost of each package in dollars. Describe the reasonable domain and range value and graph the function.
