Use the Rectangular Coordinate System: example 4.2 · Physics Playground

Exercises Graphs and straight lines

Example 4.2 from Elementary Algebra, 4.1 Use the Rectangular Coordinate System

Use the Rectangular Coordinate System: example 4.2

Plot each point:

ⓐ $(0, 5)$ ⓑ $(4, 0)$ ⓒ $(−3, 0)$ ⓓ $(0, 0)$ ⓔ $(0, −1)$ .

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
1. ⓐ Since $x = 0$ , the point whose coordinates are $(0, 5)$ is on the y-axis.
2. ⓑ Since $y = 0$ , the point whose coordinates are $(4, 0)$ is on the x-axis.
3. ⓒ Since $y = 0$ , the point whose coordinates are $(−3, 0)$ is on the x-axis.
4. ⓓ Since $x = 0$ and $y = 0$ , the point whose coordinates are $(0, 0)$ is the origin.
5. ⓔ Since $x = 0$ , the point whose coordinates are $(0, −1)$ is on the y-axis.
