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

When you know that a relationship is proportional and you know one ordered pair that is not (0,0) you can find another (any) pair x,y by doing y / x = constant.

So, with the given pair you find the ratio y / x. Suppose this ratio is:

y / x = k

Now you multiply any x-value times k to find the correspondant y-value.
