**Direct Variation A function in the form ,where**

, is a direct variation. The constant of variation, , is the coefficient of The variables and are said to vary directly with each other.

5
**Is it direct variation? To discover this, just solve for y.**

Find the constant of variation

6
**Is it direct variation? Try these please.**

Remember: To discover this, just solve for y. yes no no

7
**Write the equation from a point**

Given point: (4, -3)

8
**Write the equation from a point**

Your turn! Point (-3, -6) Point (12, -8)

9
**Direct Variation Tables**

Use the ratio, , to tell whether y varies directly with x. Why? Since, k = If yes, then write the direct variation equation. x y -2 1 4 8 -4 -10 5
