B. TRUE OR FALSE 1. In the Direct Variation, as one quantity increases the other quantity decreases. 2. In the Variation statement, K is the constant of Variation. k 3. The equation y=- shows Inverse Variation. 4. Given y varies directly as X and Y= 15 when x = 5, the value of K or the constant of variation is 3. 5. Joint Variation involves 2 variables only. 6. If Y varies jointly as X and z, the value of Y when x=3 and z=9 and k= 6 is 162. 7. In the inverse Variation, as one quantity increases, the other quantity decreases.​
