Rational Numbers on a Coordinate Plane
Overview
We know that rational numbers appear before and after zero on a number line. The negative sign (-) represents numbers that come before zero. Numbers that come after zero are positive.
These numbers can also appear on a coordinate plane. A coordinate plane is made up of two number lines: one horizontal number line called the x-axis and one vertical number line called the y-axis.
We can see that a coordinate plane has negative and positive numbers.
How do you plot negative numbers?
You plot negative numbers the same way you plot positive numbers. You find the
number, including the negative sign (-) on the axis. For example
Plot the ordered pairs on a coordinate plane
(-2, 2)
| To find -2 we travel to the left on
the x-axis (before the zero) |
|
|
To find 2, we travel up on the y-axis (after the zero) |
