What is the length of the line segment joining the points (1, 2) and (1, 5)?

What is the length of the line segment joining the points (1, 2) and (1, 5)?

Step 1: Identify the two points given in the question. The points are (1, 2) and (1, 5).
Step 2: Notice that both points have the same x-coordinate (1). This means the line segment is vertical.
Step 3: To find the length of the vertical line segment, subtract the y-coordinates of the two points. The y-coordinates are 2 and 5.
Step 4: Calculate the difference: |5 - 2|. This means you take the absolute value of the difference between 5 and 2.
Step 5: Perform the calculation: 5 - 2 = 3.
Step 6: The length of the line segment is 3.
