The video tutorial explains how to determine the distance between two points using the distance formula. It begins with an introduction to labeling points with subscripts for clarity. The distance formula is presented, and its application is demonstrated through an example problem. The tutorial provides a detailed walkthrough of the calculation process, emphasizing the importance of order of operations and handling of negative numbers.

Why do we use subscripts like X1, Y1, X2, Y2 when labeling points?

• To assign numeric values to the points

• To distinguish between different points

• To confuse students

• To make calculations easier

What is the purpose of the distance formula?

• To label points with subscripts

• To determine the distance between two points

• To calculate the slope of a line

• To find the midpoint between two points

In the distance formula, what operation is performed after subtracting the coordinates?

• Squaring

• Multiplication

• Division

• Addition

What is the result of squaring a negative number?

• A positive number

• The same negative number

• Zero

• A negative number

What is the final step in solving the distance formula?

• Adding the coordinates

• Taking the square root

• Subtracting the coordinates

• Multiplying the coordinates
