Question

The numbers of hours worked, x , and the total dollars earned, y have a strong positive relationship.

Explain what it means to have a strong positive relationship in this situation.

Answer 1

Strong positive relationship means there is direct variation between x and y .

• If x increases then y also increases.
• If x decreases then y also decreases

`\\ \sf\Rrightarrow x\propto y`

`\\ \sf\Rrightarrow (x)/(y)=k`
