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 ] .
It is not possible to answer the question with no information about which ordered pairs!
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.
