In the image, the task is to find the distance between points $A$ and $C$ on the number line.

From the number line:

• $A$ is located at $-8$
• $C$ is located at $4$

To find the distance between two points on a number line, we use the formula: $\text{Distance} = |C - A|$

Substituting the values: $\text{Distance} = |4 - (-8)| = |4 + 8| = |12| = 12$

Therefore, the distance $AC$ is 12 units.

Would you like more details or have any other questions?

Here are five related questions:

1. How would you calculate the distance between points $B$ and $D$?
2. Can you explain why the absolute value is used when finding distances?
3. What is the distance from $A$ to $B$?
4. How would you represent the distance between any two points $X$ and $Y$ algebraically?
5. What are some real-life applications of finding distances on a number line?

Tip: Always double-check whether both points are positive or negative, as that affects the distance calculation.
