A scientist investigates four physical relationships, represented by the graphs W, X, Y, and Z below.
W
X
Y
Z
Match each relationship to the corresponding graph letter.
| Relationship | Graph letter |
|---|---|
| y∝xy \propto xy∝x | |
| y∝1x\displaystyle y \propto \frac{1}{x}y∝x1 | |
| y∝x2y \propto x^2y∝x2 | |
| y∝1x2\displaystyle y \propto \frac{1}{x^2}y∝x21 |
