Applying the distance formula to find the distance between two points

The video tutorial explains how to determine the distance between two points using the distance formula. It introduces the concept of labeling points with subscripts for clarity and provides a detailed example problem. The tutorial emphasizes the importance of understanding the formula and applying it correctly, highlighting common pitfalls and the order of operations in calculations.

Why do we use subscripts like X1Y1 and X2Y2 when labeling points?

• To confuse students

• To assign numeric values to the points

• To distinguish between different points

• To make calculations easier

What is the purpose of the distance formula?

• To determine the distance between two points

• To label points on a graph

• To calculate the slope of a line

• To find the midpoint between two points

What is the first step in applying the distance formula?

• Square the differences

• Subtract the y-coordinates

• Label the points with subscripts

• Take the square root

In the example provided, what is the result of -5 + 4?

• -9

• 0

• 1

• -1

What is the final result of the distance calculation in the example?

• Square root of 49

• Square root of 16

• Square root of 25

• Square root of 37
