On a graph, you have two axis, x and y. In an ordered pair, the first number is the x coordinate, and the second number is the y coordinate.
On the x-axis, if the x-coordinate is negative then you go left. If the x-coordinate is positive, then you go right.
On the y-axis, it works the same way. If the y-coordinate is negative, you go down, but if it is positive, then you go up.
For example, if you had the ordered pair (-7,4), then you would go left seven spaces on the x-axis and up four spaces on the y-axis.

Ordered pairs are used to locate points on the graph. The first number in an ordered pair corresponds to the horizontal axis, and the second corresponds to the vertical axis.
hx = -2x2We have to assume that 'h' is some constant that you know but we don't.The graph of this equation contains no ordered pairs, since there's only one variable.If you must graph it, then the space you need to use is the number line. The twosolutions to the equation are points on the number line ... one point at [ zero ],and the other at [ - h/2 ] .
You can easily test any ordered pair that someone may offer you, to determinewhether the pair is part of the graph of the function [ y = 3 - x ].Simply check to see whether the sum of the two members of the ordered pair is 3.If yes, and only if yes, then the pair is part of the graph of the function.
It is not possible to answer the question with no information about which ordered pairs!
Graph of an equation.
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.
Yes.
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.
Infinitely many. Each and every point on the graph gives rise to an ordered pair.
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.

on a graph that goes up to 4 only, In what quadrant is (25, -18)?
Ordered pairs are used for many things. Anytime you graph a point on a cartesian coordinate system, you have an ordered pair. In fact, all of R^2 is made up of ordered pairs. When you put a value in a function and get one out, you have an ordered pair
They represent two points.
You might be thinking of the scattergram.
