Question

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?

Answer 1

If you are given one order of pairs x1 and y1, the proportional relationship goes x1/x2=y1/y2
if one inceases x time the ther one also increases x times.

Answer 2

k(x,y) is proportional to ordered pair
`(x,y)\\eq (0,0)`

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
`(x,y)\\eq (0,0)` then we can take another pair as
`k(x,y)` where k is a constant and can be either positive or negative .
