How can you use ordered pairs to locate points in a coordinate plane?

An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

How do you find ordered pairs?

Ordered pairs are often used to represent two variables. When we write (x, y) = (7, - 2), we mean x = 7 and y = - 2. The number which corresponds to the value of x is called the x-coordinate and the number which corresponds to the value of y is called the y-coordinate.

How do you plot an ordered pair of points on a Cartesian plane?

To plot the point (−2,4), begin at the origin. The x-coordinate is –2, so move two units to the left. The y-coordinate is 4, so then move four units up in the positive y direction. To plot the point (3,3), begin again at the origin.

What ordered pairs are not functions?

In order for a relation to be a function, each x must correspond with only one y value. If an x value has more than one y-value associate with it -- for example, in the relation (4, 1), (4,2), the x-value of 4 has a y-value of 1 and 2, so this set of ordered pairs is not a function.

What are ordered pairs in math?

An ordered pair is a pair of numbers, (x,y) , written in a particular order. The ordered pair (x,y) is not the same ordered pair as (y,x) .

Is the set of ordered pairs a function Why or why not?

The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates. These have the same first coordinate and different second coordinates. ...
