To solve the system of equations given by:

  1. \( y = |x| - 1 \)
  2. \( y = x + 3 \)

we need to find the points where these two graphs intersect.

Step 1: Set the equations equal to each other:

\[ |x| - 1 = x + 3 \]

Step 2: Solve the absolute value equation:

Case 1: \( x \geq 0 \)

In this case, \( |x| = x \). The equation becomes:

\[ x - 1 = x + 3 \]

Subtracting \( x \) from both sides:

\[ -1 = 3 \]

This is not true, so there are no solutions in this case.

Case 2: \( x < 0 \)

In this case, \( |x| = -x \). The equation becomes:

\[ -x - 1 = x + 3 \]

Adding \( x \) to both sides:

\[ -1 = 2x + 3 \]

Subtracting 3 from both sides:

\[ -4 = 2x \]

Dividing by 2:

\[ x = -2 \]

Step 3: Find \( y \) using either original equation:

Using \( y = x + 3 \):

\[ y = -2 + 3 = 1 \]

Conclusion:

The solution to the system of equations is:

\[ \boxed{(-2, 1)} \]

Thus, the intersection point, or the solution to the system, is at \((-2, 1)\).
