Question

Solve the equation for the y-value and choose whether it is a direct variation or inverse variation.

xy = 7

A. direct variation
B. inverse variation

Answer 1

`\\ \sf\longmapsto xy=7`

• Take x to right and divide

`\\ \sf\longmapsto y=(7)/(x)`

Hence

.
`\\ \sf\longmapsto y\propto (1)/(x)`

Inverse variation
