Chapter 9, Problem 1RE

To determine

To plot: The point $A=\left(5,-2\right)$ in a rectangular coordinate system.

Explanation of Solution

Procedure used:

To plot a point on the rectangular coordinate system:

1. Start at the origin.

2. Count to the left or right the number of units of the first signed number (x-coordinate) in the ordered pair.

3. From the ending point of Step 2, count up or down the number of units of the second signed number (y-coordinate).

4. Place a dot to show the point and write the coordinates beside the point.

Graph:

Given point is $A=\left(5,-2\right)$.

To plot a point means to show its location on the rectangular coordinate system.

The point $A=\left(5,-2\right)$ plotted in a rectangular coordinate system is as shown below in Figure 1.

From Figure 1, it is observed that the point $A=\left(5,-2\right)$ is plotted by moving 5 units to the right from the origin and from there moving down by 2 units on a rectangular coordinate system.
