Chapter 3: Q. 3.9 (page 238)

Graph the equations
(a) $x = 5$
(b) $y = - 4$

Short Answer

Expert verified

The required graphs are

And

Step by step solution

Step 1. Given Information

The given equations are $x = 5$ and $y = - 4$

Part(a) Step 1. Explanation and Graph

The equation has only one variable $x$ which is always equal to 5. We will create a table where $x = 5$ and can put any value in $y$ .

x	y
5	2
5	4

The required graph is a vertical line passing through the $x$ -axis at 5.

Part(b) Step 1. Explanation and Graph

The equation has only one variable $y$ which is always equal to $- 4$ . Thus, we will create a table where $y = - 4$ and can put any value in $x$ .

x	y
1	$- 4$
2	$- 4$

The required graph is a horizontal line passing through the $y$ -axis at $- 4$ .
