How to do the Distance Formula

The video tutorial introduces the distance formula, explaining its purpose and how to apply it to find the distance between two points on a coordinate plane. It provides a detailed example calculation, highlights common mistakes, and offers a practice problem for students to solve independently.

What is the primary purpose of the distance formula?

• To find the midpoint between two points

• To find the area of a triangle

• To calculate the slope of a line

• To determine the distance between two points

In the example problem, what is the first step after identifying the points?

• Calculate the slope

• Label the coordinates

• Find the midpoint

• Draw a graph

What common mistake do people make when squaring a negative number in a calculator?

• Not using parentheses around the negative number

• Forgetting to add the numbers first

• Using the wrong formula

• Multiplying instead of squaring

What should you ensure after squaring all terms in the distance formula?

• The terms should be in ascending order

• All terms should be positive

• All terms should be negative

• The terms should be in descending order

What is the approximate distance calculated in the first example problem?

• 6.7

• 5.6

• 7.8

• 8.9

In the second example, what is the result of 16 squared?

• 128

• 196

• 324

• 256

What is the approximate distance calculated in the second example problem?

• 20.5

• 24.7

• 18.4

• 22.6
