Direct Variation Worksheet 1. Which equation is not an example of a direct variation? A. y = -x+1 B. y = -X 16 C. y = 4X D. V = -9x 2. Which equation is not an example of a direct variation? A. Y = X B. 2x + 3y = 0 C.y = =x D. 5x + 6y = 30 Name the constant of variations(k) for each equation. 3. y = 5x 4. y = =x 5 . y = 7x Write a direct variation equation that relates the two variables. Then solve. 6. Suppose y varies directly as x, and y= 16 when x - 8. Find y when x = 16. 7 Suppose y varies directly as x, and y - 21 when x = 3. Find x when y = 42. 8. Suppose v varies directly as g, and v = 36 when g = 4. Find v when g = 11
