#### Answer

R = k(T - $T_{e}$)

#### Work Step by Step

If variables vary directly then y = x, so as one increases then the other increases. If variables vary inversely then y = $\frac{1}{x}$, so as one increases then the other decreases. Using the description, R = k(T - $T_{e}$) where k is a constant.
