Question
**Problem Statement:**

Given the graph of triangle \( \Delta XYZ \) with the coordinates \( X(1, 3) \), \( Y(4, -1) \), and \( Z(5, 6) \), determine which statement proves that \( \Delta XYZ \) is an isosceles right triangle.

**Graph Description:**

The graph represents a coordinate plane with triangle \( \Delta XYZ \) plotted. The vertices \( X \), \( Y \), and \( Z \) are labeled:

- \( X(1, 3) \)
- \( Y(4, -1) \)
- \( Z(5, 6) \)

**Task:**

Select the correct statement that proves \( \Delta XYZ \) is an isosceles right triangle from the following options:

1. \( XZ \perp XY \)
2. \( XZ = XY = 5 \)
3. The slope of \( XZ \) is \( \frac{3}{4} \), the slope of \( XY \) is \( -\frac{4}{3} \), and \( XZ = XY = 5 \)
4. The slope of \( XZ \) is \( \frac{3}{4} \), the slope of \( XY \) is \( -\frac{4}{3} \), and the slope of \( ZY \) is 7
