A coordinate graph is a graph of pairs of numbers that represent real-life situations.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
They represent two points.
I'm not sure what you are asking. Sums represent either an increase of one quantity by another quantity, or a combination of two quantities. Two of anything is a pair. Did you mean to ask, "What are sums of pairs?" One common use of a pair in mathematics is an ordered pair, such as (2,3). This can represent a coordinate in a graph, or it can represent a vector. If pairs represent a vector, you add the components, so (2,3) + (40,50) = (42, 53).
80 has 5 factor pairs.

I'd hate to give you a definition like, "Related pairs of numbers are pairs of numbers that are related" so let's just go with an example. Let the first number of a pair represent a quantity of bicycles. Let the second number represent the number of tires per bicycle. With 1 bicycle you would have 2 tires, with 2 you would have 4 and so on. (1,2)(2,4)(3,6)(4,8) are related pairs of numbers.
The factor pairs of 20 are pairs of numbers that can be multiplied together to give 20. The factor pairs of 20 are (1, 20), (2, 10), and (4, 5). These pairs represent all the possible combinations of numbers that can be multiplied to equal 20.

The usual type of graph with an x axis and a y axis is officially known as the Cartesian Coordinate System, after its inventor, Rene Descartes.
If there are n numbers in the group, there aren2 ordered pairs if the numbers can be repeated,n*(n-1) ordered pairs if the numbers cannot be repeated,n2/2 pairs if the numbers can be repeated,n*(n-1)/2 pairs if the numbers cannot be repeated.
The numbers 2 and 3 are consecutive prime numbers. Are there other pairs of prime numbers which are consecutive numbers?
They represent two points.
Chromosomes are arranged in pairs and they are not yet named, but each of the pair is identified by numbers 1 to 22 (ie., twenty-two pairs of autosomes) and the 23rd pair by xx (in females) or xy (in males) to represent gonosomes (sex chromosomes).
the answer is ............23
Assuming the 36 numbers are all different, there are 36*35/2 = 630 pairs.
The factor pairs of 168 are the pairs of numbers that can be multiplied together to give the product 168. These pairs include (1, 168), (2, 84), (3, 56), (4, 42), (6, 28), (7, 24), (8, 21), and (12, 14). Factors are numbers that divide evenly into a given number, and in the case of 168, these factor pairs represent all the possible combinations of factors that multiply to 168.
