Using 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 begins with labeling the points as per the formula, followed by applying the formula to calculate the distance. The tutorial then demonstrates simplifying the calculation using order of operations and discusses further simplification of the result.

What is the first step in using the distance formula to find the distance between two points?

• Calculate the midpoint of the points

• Label the points as X1, X2, Y1, and Y2

• Find the slope of the line

• Determine the coordinates of the origin

Which of the following represents the correct distance formula?

• Square root of (X2 - X1)^2 + (Y2 - Y1)^2

• X2 - X1 + Y2 - Y1

• X2 + X1 + Y2 + Y1

• Square root of (X2 + X1)^2 + (Y2 + Y1)^2

If X2 is 8 and X1 is -2, what is the result of X2 - X1?

• 6

• 8

• 10

• 12

What is the result of squaring the difference between Y2 and Y1 if Y2 is 3 and Y1 is -1?

• 4

• 9

• 12

• 16

What is the simplified form of the square root of 116?

• 2√29

• 4√29

• √58

• √116
