Answer:
Step-by-step explanation:
- The products of corresponding x- and y- values of an inverse variation function are constant.
- As x increases, y also increases.
-The product of the coordinate pairs are not equal: (165)(198)=32,670 and (170)(204)=34,680
Divide: 9x 2/36 - 4y 2/36 = 36/36. Simplify: x2/4 - y2/9 = 1. Then do (x-0) 2/4 - (y-0)2 =1. Hyperbola.
