We are asked which set of numbers best describes the values of the variable y, which is the year, and p, the median selling price of a house that year.
00:11
An example for a value for the variable y for the year could be the number 2019, which is a year.
00:18
And an example for the price could be something like 500 ,000.
00:27
Now let's take a look at what set of numbers best describes the value of the year, why.
00:35
Years have to be positive numbers.
00:38
They have to be positive counting numbers.
00:40
There can't be a decimal for a year, and a year can't be zero or a negative number.
00:44
Therefore, we know that y is best represented by the natural numbers, which are the positive counting numbers...
