To solve this problem, we need to find an absolute value equation that matches the given points on the number line.

The two points shown are at $x = -3$ and $x = 1$. In an absolute value equation of the form $|x - a| = b$, $a$ is the midpoint of these two numbers, and $b$ is the distance from the midpoint to either of the points.

1. Step 1: Find the midpoint

   • The midpoint between $-3$ and $1$ is: $\frac{-3 + 1}{2} = \frac{-2}{2} = -1$ So, the midpoint is $-1$.

2. Step 2: Find the distance from the midpoint

   • The distance from $-1$ to either $-3$ or $1$ is: $|-3 - (-1)| = |1 - (-1)| = 2$ Therefore, the distance is 2.

3. Step 3: Write the equation

   • The absolute value equation that satisfies this is: $|x + 1| = 2$ (since $x + 1 = x - (-1)$).

Thus, the correct answer is: $\boxed{|x + 1| = 2}$
