They show how one variable relates varies with another. Direct variation indicates a linear relationship between two variables. Direct variation is also called direct proportionality. Two variables that increase and decrease by the same amount are directly proportional.
Solve each problem involving direct variation. 11) If y varies directly as x, and y = 5 2 when x = 15, find y when x = 3. 12) If y varies directly as x, and y = 6 when x = 5, find y when x = 10. 13) If y varies directly as x, and y = 14 when x = 3, find y when x = 6. 14) If y varies directly as x, and y = 3 when x = 18, find y when x = 9. 15 ...
1. All the points lie on a line. 2. The line passes through the origin. This type of relationship is called direct variation. You can write an equation to describe the relationship between t and w. w 2t. Wrist is twice thumb. 3 ACTIVITY: Drawing a Graph. Work with a partner. Use the information from Activity 1 to draw a graph of the relationship.
Step 1: Assign variables: Let i = income and h = hours Step 2: Determine the constant of variation. Formula: ! $ % &' ( $ % ) ". *+++ $ % , k = 2250 (constant of variation) Step 3: Write the direct variation equation. Formula: y = kx or i = kh. i = 2250h (direct variation equation) b.
