Determine if the table represents a direct variation.. 1 In the absence of case - law on how the new proportionality test is working in practice, how should you argue proportionality at assessment (with examples of successes and failures, difficulties exp the tables in your notebook. .

Objective: I will . identify the same value relating the measures of x and the measures of y in a proportional relationship as the constant of proportionality and recognize it as the unit rate in the context of a given situation. . Magumba. Lecture 3 . Proportionality. Ratios. If the ratio of A:B is 1:3 then A = 1/3 of B. For instance if you were to divide 20 oranges between A and B in the ratio 1:3 it means you have a total of 1 + 3 or 4 equal parts and each part is equal to 20/4 or 5 oranges, A gets 1 * 5 oranges and B gets 3 * 5 oranges. 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. (. 0. ,0). (1,45). (2,90). (3,135). (4,180). In this lesson you . will learn how to determine the constant of proportionality in graphs. . by finding the ratio of y to x. . (2,5). (2,. -5). (-2,. 5). Directly Proportional. Directly proportional: as one amount increases, . another amount increases at the same rate. .. Hence, the straight line when we graph information. Directly Proportional. Example: you are paid $20 an hour. 1. 160 words typed in 4 minutes. 2. $27.40 for 4 hours of work. 3. $12.66 for 8 packages of juice boxes. 4. $284 for a 4 day car rental. 5. 560 heartbeats in 6.5 minutes. 6. jogging 3.5 km in 30 minutes. Learning Target. I will be able to represent proportional relationships by equations.. Constant of Proportionality. The graph of a proportional relationship is a straight line that passes through the origin. . (. a.k.a. : the unit rate).
