I need a formula for something, but I'm not sure exactly what it's called. The last time I did any of this math was two years ago in precal and I honestly don't remember it! I know there was some formula and if it weren't summer I would go to my teacher and ask.


The problem is this:


I have three times: 3.9,20.1,43.8

and then their relation heats: 118.3,327.9,591.8


I need to find the time where the heat is 700, but I don't remember the formula for finding the relation.

If anyone can help me with this it would be much appreciated.
