That would depend on the given system of linear equations which have not been given in the question
Each ordered pair is made up of two numbers. A linear graph has an infinite number of pairs. An easy way to see this is look at the line y=x. This is a linear graph and any two of the same numbers will work! So there are an infinite number of ordered pairs.
They represent two points.
Y2-y1 x2-x1
When you have two points of a line, you can connect the dots.
There have to be two (or more) ordered pairs for an average rate of change to make any sense. Your question does not.
Cartesian product is the name that refers to the set of the ordered pairs. The Cartesian product of two sets A and B is AB.
In order to draw a straight line, two unique ordered pairs are needed. This is because two unique points determine a line and an ordered pair represents a point.
The y-values for the two ordered pairs would have to be the same (for example, (3,1) and (6,1) would be such a set of ordered pairs). Because the slope of a line is (y1-y2)/(x1-x2), for the slope to be zero, y1=y2.

(7, 6) and (14, 12) are two obvious candidates.
You might be thinking of the scattergram.
