How am I supposed to graph the following functions?

1. A wholesaler is buying auto parts. He has $200 to spend. He receives 5 parts free with the order. The number of parts y he can buy, if the average price of the parts is x dollars, is y = 200/x + 5.

a. Graph the function.

A: ?

2. A caterer has $100 in her budget for fruit. Slicing and delivery of each y = 100/x + 5 represents the number of pounds y she can buy.

a. Graph the function.

A: ?

well, shoot. How do you graph any function? You pick some values for x, compute the value for y, and plot some points. Then draw a curve through the points.

For y = 200/x + 5, start with x=1 and figure a few points.

x y
1 205
2 105
3 71.7
4 55
and so on.
