Chapter 8, Problem 24CT

To determine

To graph:

The given linear inequality.

Answer to Problem 24CT

The graph of our given inequality would look like:

  

Explanation of Solution

Given:

An inequality:

  $x<7$

Calculation:

First of all, we will replace the inequality sign with an equal to sign to graph the boundary line as: $x=7$ . Since we have a less than sign $(<)$ , so our boundary line will be a dotted line as shown below:

  

Now, we will test a point $(0,0)$ to shade in the correct region.

  $\begin{array}{l}x<7(\text{Given inequality)}\\ 0<7(\text{Substituting }x=0)\end{array}$

Since point $(0,0)$ satisfies our given inequality, so we will shade in the region, which includes point $(0,0)$ .

Upon shading in the region that includes point $(0,0)$ , we will get our required graph as shown below:
