### Using the Pythagorean Theorem to Find Distance Between Points

**Problem Statement:**
How can we use the Pythagorean theorem to find the length of segment AB, or in other words, the distance between A (-2,1) and B (3,3)? Find the distance between A and B.

**Graph Explanation:**
The graph provided is a Cartesian coordinate system with two points labeled: A at coordinates (-2, 1) and B at coordinates (3, 3). A line segment connects these two points. The x-axis and y-axis intersect at (0,0), and the grid lines help indicate the location of the points and the segments in between.

**Steps to Solve:**

1. **What would you do first?**
   - Determine the horizontal and vertical distances between the two points (A and B) on the grid.
     - To find the horizontal distance (change in x-coordinates), subtract the x-coordinate of A from the x-coordinate of B: 
       \[
       |3 - (-2)| = |3 + 2| = 5.
       \]
     - To find the vertical distance (change in y-coordinates), subtract the y-coordinate of A from the y-coordinate of B: 
       \[
       |3 - 1| = 2.
       \]

2. **What would your next step be?**
   - Use the Pythagorean theorem to find the length of the line segment AB. The Pythagorean theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
     - Here, the distance between A and B (denoted as \(d\)) is the hypotenuse, the horizontal change (5) and vertical change (2) are the other sides:
       \[
       d^2 = 5^2 + 2^2.
       \]
     - Calculate the squares:
       \[
       d^2 = 25 + 4.
       \]
     - Sum the squares:
       \[
       d^2 = 29.
       \]
     - Take the square root of both sides to solve for \(d\):
       \[
       d = \sqrt{29}.
       \]
