A)how do I find an inverse variaton equation that model:

Length(in.) 4 6 8 9 10

Breaking weight(pennies)24 16 13 11 9

B)Explain how your equation shows that breaking weight decreases as length increases. Is this pattern reasonable for this situation? Explain.

A neat math trick on inverse relationships is this trick:

IF A is inversley related to B, then

A= constant/B where constant is the constant of proportionality.

Then multiplying both sides by B, then

A*B= constant.

So check your data, if length*Weight stays constant, it is inversely related.

I will do a couple for you.

4*24= ...96

6*16= ...96

check the rest.
