Direct Variation Exercises
Example 1
If y varies directly with x, and the constant of variation is k = 5, find y when x = 40.
Example 2
If y varies directly with x, and the constant of variation is k = ⅓, find y when x = 45.
Example 3
If y varies directly with x, and y = 64 when x = 8, find y when x = 12.
Example 4
If y varies directly with x, and y = 72 when x = 6, find y when x = 2.
