Final answer:
In order to graph the inequality x ≤ 3 on a number line, make a filled circle at 3 and shade the portion to the left. The solution set in interval notation is (-∞, 3], which is Graph A.
The answer is option ⇒A. Graph A
Step-by-step explanation:
To graph the solution set of the inequality x ≤ 3 on a number line and write it in interval notation, we can follow these steps:
- 1. Draw a number line with zero (0) in the middle.
- 2. Mark the point 3 on the number line.
- 3. Shade the region to the left of the point 3 since the inequality x ≤ 3 includes all values less than or equal to 3.
- 4. Indicate that the point 3 is included in the solution set by making it a filled circle or square on the number line.
- 5. Write the solution set in interval notation.
- Since the shaded region includes all values less than or equal to 3, we can write the solution set as (-∞, 3].
Based on these steps, the correct graph would be Graph A, which correctly shows the shaded region to the left of the point 3 and includes a filled circle or square at the point 3.
The answer is option ⇒A. Graph A
