x-axis
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.
The abscissa
In coordinated geometry it is x followed by y
It is called the abscissa.

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.
The abscissa
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 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.
