# Write a direct variation equation for the relationship between time and distance

### Solving Direct Variation Problems

Direct Variation – a special type of linear relationship that can represented by a function If you can write the equation in the form y = kx, where k ≠ 0, then it is a direct variation. Then graph. Step 1 Write a direct variation equation. distance. = 2 mi/h. times. hours. y. = x. Example: Graphing Direct Variation. Joke Time. Use the conversion factors in the table to make each conversion. The equation d = t shows the direct-variation relationship between the time and maximum legal distance traveled on most two-lane highways in Canada. What is the shortest amount of time in which a person can legally drive 15 kilometers? (1. The graph of a direct variation will ALWAYS go through the origin (0,0). Write an equation for the relationship between the time and distance. How far can you .

Сьюзан на экране тянулась к нему, плача и смеясь, захлестнутая волной эмоций. Вот она вытерла слезы. - Дэвид… я подумала… Оперативный агент Смит усадил Беккера на сиденье перед монитором. - Он немного сонный, мадам.
