Two numbers written in a certain order.
Usually written in parentheses like this: (4,5)

Example:

For a number decaying exponentially, this is how long it takes to split in half.

Example:
If you have 20 grams of something and its half-life is 5 years, then after 5 years you will only have 10 grams. After another 5 years, it will decay in half again, leaving you with 5 grams.
The value can never reach zero: it will simply keep dividing in half until it is too small to see.

How far a number is from 0, or:
The numerical value of a number, regardless if it is a positive or negative.

Example:
When you have the number -6, it is a negative number. However, it is 6 numbers away from 0, making its absolute value 6.

The value of x when the value of y is 0.

Example:
If you have the coordinate pairing (4,0), that means that x is 4 while y is 0. This means that the x intercept is 4.
