How does graphing the order pairs of a relation can help decide if the relation is a function?
If a relation can be called a function, it means that the relation maps every element to one and only one other element. If you have some ordered pairs and see that, for example, 1 maps to 4 (1,4) and 1 also maps to 7 (1,7) , you don't have a function.
Would it be easier to find the rule for a function table with 3 pairs of numbers or 4 pairs of numbers?
If it's a linear function, 3 should do, but 4 will give an extra check on you work. If the function is quadratic exponential, etc. then at least 4 pairs should be used.

What is graphing ordered pairs?
Ordered pairs are represented as functions themselves or they compose a function. They are written as (x, y) as coordinates for their respective function. For example, for the function y=2x, it contains the ordered pairs (0, 0), (1, 2), and so on by plugging in the coordinates for x and y. Where x=0, y=0 because y=2(0). Where x=1, y=2 because y=2(1). To graph ordered pairs, you must be given their respective function(s). From there, it is possible to make a chart of the x and y coordinates in that function, and plot them accordingly.
