Finding Distances Using Absolute Value

This video tutorial teaches how to use absolute value to find distances between points on a coordinate plane. It begins with a review of absolute value, explaining it as the distance from zero on a number line. The tutorial highlights common mistakes in plotting points, such as incorrect axis movement and returning to the origin. It then demonstrates plotting points and calculating distances using absolute value, emphasizing that distance is always positive. The lesson concludes by summarizing the method of finding distances between points with the same x or y values using absolute value.

What does absolute value represent?

• The negative distance from zero

• The positive distance from zero

• The total distance between two points

• The difference between two numbers
