A relation is defined as a set of ordered pairs. A function is a special kind of relation ...
The question does not contain an equation nor an inequality. There cannot, therefore be any ordered pairs which can satisfy an expression.

true
(2, 5.3) is one example.
They are all the pairs you make where (x = any number) and (y = 4).

In general you cannot. Any set of ordered pairs can be a graph, a table, a diagram or relation. Any set of ordered pairs that is one-to-one or many-to-one can be an equation, function.
You can locate any point on the coordinate plane by an ordered pair of numbers (x,y), called the coordinates.

yes because all it is telling you how to ordered pairs of numbers

I believe it is a function, because a vertical line would only cross it once.
If there are any pairs with the same second element but different first elements, then it is not a function. Otherwise it is.
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.
