PPT-5-2 Direct Variation A direct variation is a relationship that can be represented by a

y kx where k 0 The constant of variation for a direct variation k is the coefficient of x Example of direct variation The time it takes to hear thunder varies directly with the distance from lightning As the distance from lightning increases so does the time it takes you to hear the thunder. Lesson 11-6. An equation in the form of ____________________ or . ____________ . is an inverse variation,. The constant of variation is _______, the _______________ of . . x. . and . y. for an ordered pair (x, y) that solves the inverse variation.. A direct variation is represented by a ratio or equation :. or. k ≠ 0. Direct Variation – constant ratio. EX1). x. 1. 2. 3. 4. y. 3. 6. 9. 12. Determine if the table represents a direct variation..

Per 3: Extra Credit for no missing assignments. Many natural (physical) phenomena exhibit . variation. = one quantity (quantities) changing on account of another (or several) . Principle is some kind of dependence. What things can we think about that depend on another action/object? . Determine the asymptotes for:. Lesson . 3-8 . Direct, Inverse & Joint Variation. Objective: To recognize and use direct variation to solve problems. Definition:. . Y. varies directly as . x. means that . A direct variation is represented by a ratio or equation :. or. k ≠ 0. Direct Variation – constant ratio. EX1). x. 1. 2. 3. 4. y. 3. 6. 9. 12. Determine if the table represents a direct variation. If so, state the constant of proportionality. Section 5-2. Goals. Goal. To write and graph an equation of a direct variation.. Rubric. Level 1 – Know the goals.. Level 2 – Fully understand the goals.. Level 3 – Use the goals to solve simple problems.. Variation. What’s the Difference. Direct Variation. When we talk about a direct variation, we are talking about a relationship where as . x increases, . y increases. . or . decreases at a . CONSTANT. Direct Variation. When we talk about a direct variation, we are talking about a relationship where as . x increases, . y increases. . or decreases at a . CONSTANT. . RATE. .. Direct Variation. Direct variation uses the following formula:. Direct Variation. y varies directly as x if there is a nonzero constant, k, such that . y = . kx. *k is called the constant of variation. Plug in the two values you have and solve for the missing variable. A wanted poster is a poster distributed to let the public know of an alleged criminal whom authorities wish to apprehend. The poster will usually include a description of the wanted person and the crime(s) for which he/she is sought. . SOL A8. by Robert Lotze, Moody Middle School. Direct Variation.
