Yes and no.
In two-dimensional Cartesian coordinates, the answer is usually yes. So the point (4,7) has x value 4 and y value 7.
But there are other uses for ordered pairs. For example in polar coordinates a point is specified by an ordered pair (r, theta), and the second number is an angle. You need to know what context you are working in.

How do you know when an ordered pair could not be in a function?
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.
What is the second value in an ordered pair?
y
Is the absolute value of a number is always nonnegative?
The absolute value of a number is always nonnegative.
Where Place value and face value of a number is always equal at?
place value and face value of a number are always equal at ones place.
What is the first value in ordered pair and second value?
First value: abscissa, is the distance from the origin along the horizontal axis (usually the x-axis). Second value: ordinate, is the distance from the origin along the vertical axis (usually the y-axis).
