Learning how to find the distance between two points

The video tutorial explains how to use the distance formula to calculate the distance between two points. It begins with labeling the points and understanding the formula, which involves the square root of the sum of the squares of the differences in x and y coordinates. The tutorial then demonstrates plugging values into the formula and performing calculations step-by-step. The video concludes with a note on the importance of this formula in tests and a brief mention of simplifying radicals.

What is the first step when using the distance formula?

• Calculate the square root

• Label the points

• Subtract the coordinates

• Add the coordinates

Which of the following is the correct expression for the distance formula?

• Distance = (X2 + X1)^2 + (Y2 + Y1)^2

• Distance = (X2 - X1)^2 - (Y2 - Y1)^2

• Distance = (X2 - X1) + (Y2 - Y1)

• Distance = √((X2 - X1)^2 + (Y2 - Y1)^2)

What happens when you subtract a negative number in the distance formula?

• It becomes zero

• It remains negative

• It doubles the value

• It becomes a positive number

What is the result of 5 squared in the context of the distance formula?

• 15

• 20
