Answer 2

Answer:

(1) x/y remains constant.

(2)Direct proportion.

(3)x/y remain constant.

(4)It remains constant.

Step-by-step explanation:

(1)If two quantities x and y vary directly with each other then x/y remains constant. This is the characteristic of direct proportion i.e. x/y = k which is the proportionality constant. If two quantities x and y vary directly with each other, then x/y remains constant.

(2)both x and y increases or decreases together such a manner that the ratio of their corresponding value remains constant. Hence the answer is Direct proportion.

(3)If two quantities x and y vary directly with each other, then x/y remains constant. Therefore if x and y are in direct proportion then only x/y remain constant. The remaining relations are incorrect i.e. x - y, x + y and xy are not constant.

(4)If two quantities x and y vary directly with each other, then x/y = k = constant. Since, in direct proportion, both x and y increases or decreases together such a manner that the ratio of their corresponding value remains constant.

Hope i am right
