What do ordered pairs mean on a graph?
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.
Which ordered pairs are part of the graph of the function y equals 3 - x?
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.
Why is the order of the numbers in an ordered pair is important?
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.
How do you plot a point with negative coordinate?
The normal convention used in the Cartesian coordinate system is that everything above the x axis is positive and everything below the x axis is negative, and everything to the right of the y axis is positive, and everything to the left of the y axis is negative (the two axes are themselves neither positive nor negative, they represent zero). Since points on a graph are identified by an ordered number pair, giving first the value of x and then the value of y, there are two numbers; you can have two positive numbers, or you can have one positive and one negative number, or you can have two negative numbers. The point that you are graphing will be located in the appropriate quadrant of the graph. Two positives are in the upper right hand quadrant, two negatives are in the lower left hand quadrant, and a positive and a negative can be either the upper left hand quadrant or the lower right hand quadrant.
In which quadrant would an ordered pair that has a negative x-coordinate and a positive y-coordinate be plotted?
The quadrants formed by the x and y axes are numbered anticlockwise from the quadrant in which both coordinates are positive (which is quadrant I). Thus negative x and positive y is in the quadrant II.
What is the quadrant of a ordered pair that has a negative x coordinate and a positive y coordinate?
An ordered pair that has a negative x-coordinate and a positive y-coordinate (-,+) would be plotted in which quadrant?
What is an equation that you graph?
an ordered pair
How to indentify an ordered pair?
An ordered pair has to be in parentheses and there has to be a comma in between the numbers (example: (2,6). An ordered pair is for a coordinate graph.
What is a ordered pair on a graph?
The coordinates, possibly.
What do ordered pairs mean on a graph?
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.
An ordered pair that has a negative x-coordinate and a positive y-coordinate - would be plotted in which quadrant Remember to use Roman Numerals to write the quadrant numbers?
An ordered pair that has a negative x-coordinate and a positive y-coordinate would be plotted in the second quadrant (II). In this quadrant, the x-coordinate is negative and the y-coordinate is positive.
How is an ordered pair related to the coordinates on a graph?
The ordered pair IS the coordinates on the graph. If you have the ordered pair (1,2) that means the value of x is 1 and the value of y is 2, so to get to that point on a graph from the origin (center) you would move right 1 unit and up 2 units.
How do you read a line graph?
Each point on a line graph in 2-dimensional space can correspond to an ordered pair of values for two variables which is observed. Or, if it is a fitted line graph, it is an estimated ordered pair.
What is a ordered pair?
An ordered pair is a list of two numbers, in which the order matters. For example, (5, 2) is an ordered pair; this pair is not the same as (2, 5). For comparison, for the numbers in a set the order does not matter.
An ordered pair that has a negative x-coordinate and a positive y-coordinate would be plotted in which quadrant?
Upper left quadrant
How do you use an ordered pair?
An ordered pair, depending on the exact kind of math you're doing, may represent a point on a graph, a piece of data, etc. In elementary algebra, an ordered pair generally describes a point on a graph in the format (x, y).
How many ordered pairs does a linear graph contain?
Infinitely many. Each and every point on the graph gives rise to an ordered pair.
