Math CentralQuandaries & Queries


Question from Ryan, a student:

if you are given a jar of pennies and you had to find the weight of one penny without opening the jar.when you graph it, You have to y= the mass of the container and x= number of coins
you use the slope to find the weight of the penny how would u go about doing that?

Hi Ryan.

If you draw a line on a graph, then that means for any value of x, there is a corresponding value of y, right?

So if x is the number of pennies and you are interested in 1 penny, you look at the graph where x=1 and find the corresponding value of y.
