If you know that a relationship is a proportional and are given one ordered pair that is not (0,0) how can you find another pair?

k(x,y) is proportional to ordered pair

Step-by-step explanation:

We know that two things are said to be proportional, if change in one thing brings similar change in another thing i.e we say x and y are said to be proportional if any of the following condition holds:

1. Increase in x leads to increase in y

2. Decrease in x leads to decrease in y.

For example increase in price of sugar leads to increase in price of tea. So, price of sugar and price of tea are proportional.

Let one ordered pair be then we can take another pair as where k is a constant and can be either positive or negative .

a is the right answer
