Answer: The first number refers to the x coordinate (horizontal). The second number is the y coordinate (vertical).
Answer: Actually, it is customary to use "x" and "y" in that order, but any variables may be used. For example, for some purposes, time is used on the horizontal axis. In any case, if the ordered pair refers to coordinates, the first number is called the "abscissa", and the second one, the "ordinate".

ordered pair
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.

They are the set of abscissae.
This first number in an ordered pair is x. And since x is always -5, all these work. (-5,0),(-5,1),(-5,2),(-5,3),(-5,4)

the first number in an ordered pair is the x coordinate it is one of the values that the independent variable has taken on
The first number in an ordered pair is the x-coordinate. Your very welcome i came along and told you the answer aren't you! <3

ordered pair
Evaluate the function at the first number in the pair. If the answer is not equal to the second value, then the ordered pair cannot be in the function.

In coordinated geometry it is x followed by y
