Infinitely many. Each and every point on the graph gives rise to an ordered pair.

Equivalently, how many points does any linear graph contain? Equivalently, how many points does any line contain? Infinity.
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.
graph the ordered pairs (4, -2) AND (1, -1) AND CONNECT TO FORM A line. Which quadrant contains no point for this linear function? Explain your answer
A continuous linear function produces a straight line graph that can be extended indefinitely in either direction. If the two ordered pairs are plotted on a graph then a straight line can be drawn joining these points. If that line is extended beyond both ends then there are no set limits and the function becomes continuous.
If you are talking about the things in the perentheses, (5,-9), they are called ordered pairs. Ordered pairs help you find a location on a coordinate graph.
