This lesson builds upon the previous lesson's derivation of the distance formula, and demonstrates how to use the formula to find the distance between two points. The instructor provides several examples, showing how to correctly set up and simplify the formula. The lesson also highlights the importance of understanding the order of the values in each parenthesis, and offers tips for estimating distances and rounding answers. Overall, this lesson provides a clear and accessible explanation for using the distance formula in practical applications.
Shows several examples using the distance formula to find the distance between 2 points.
What is the distance between (-3, -6) and (4, -8)?
What is the distance between (0, 4) and (-9, 3)?
What is the distance between (-4, 5) and (2, 1)?
What is the distance between (1/2, -3) and (4 1/2, 6)?
What is the distance between (-6, -5) and (-8, -8)?
Does it matter what order you put values into the distance formula?
