Example 11.4 from Prealgebra, 11.1 Use the Rectangular Coordinate System

Use the Rectangular Coordinate System: example 11.4

Plot each point:

ⓐ $(−5, 2)$
ⓑ $(−5, −2)$
ⓒ $(5, 2)$
ⓓ $(5, −2)$

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
As we locate the $x -coordinate$ and the $y -coordinate,$ we must be careful with the signs.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Plot each point:

ⓐ $(4, −3)$
ⓑ $(4, 3)$
ⓒ $(−4, −3)$
ⓓ $(−4, 3)$

How did it go?
