The problem in the image can be broken down as follows:

We are given two points $A$ and $B$ on a number line. The distance between $A$ and $B$ is 11, i.e., $AB = 11$, and we know that point $B$ is located at 8.

Step-by-step solution:

The distance between two points on a number line is the absolute difference between them: $|A - B| = 11$ We know that $B = 8$, so: $|A - 8| = 11$

To solve this, we need to consider two cases, since the absolute value gives two possible solutions:

1. $A - 8 = 11$
2. $A - 8 = -11$

Case 1:

$A - 8 = 11 \implies A = 11 + 8 = 19$

Case 2:

$A - 8 = -11 \implies A = -11 + 8 = -3$

Thus, the possible locations for $A$ are 19 and -3.

Final Answer:

$A$ could be located at 19 or -3.

Tip: Always check both the positive and negative cases when solving absolute value equations.
