Definition: Relation. A relation from a set A to a set B is a subset of A × B. Hence, a relation R consists of ordered pairs (a, b), where a ∈ A and b ∈ B. If (a, b) ∈ R, we say that is related to , and we also write aRb. Remark. We can also replace R by a symbol, especially when one is readily available.

Oct 12, 2023 · The ordered pair is used to locate a point in the coordinate system. The first integer in the ordered pair s called either x-coordinate or abscissa and the second integer is ordinate or y-coordinate. Equality of Ordered Pairs. Two ordered pairs are said to be equal if and only if the corresponding 1st components and 2nd components are equal.
So this is not notation, this is a definition of what the ordered pair is in set theory. We are defining an object, which we call "$(a,b)$", to be the given set. It's not merely how we are writing the ordered pair, is what the ordered pair is if you are interested in actually seeing
Ordered pairs are a fundamental part of graphing. Ordered pairs make up functions on a graph, and very often, you need to plot ordered pairs in order to see what the graph of a function looks like. This tutorial will introduce you to ordered pairs!

Performing dilations. To dilate a point on a coordinate plane, you multiply its coordinates by a scale factor. The scale factor is a positive number that tells you how much to enlarge or shrink the point. If the scale factor is greater than 1, the point moves away from the origin. If the scale factor is less than 1, the point moves closer to ...
