Distance and Midpoint on the Number Line

The video tutorial covers how to calculate distances and midpoints on a number line and a Cartesian plane. It explains the process of finding distances between positive and negative numbers, as well as between points with x and y coordinates. The tutorial also provides methods for calculating midpoints by finding the distance and dividing it by two. Practical examples are used to illustrate these concepts, ensuring a clear understanding of the mathematical principles involved.

How do you find the distance between two positive points on a number line?

• Subtract the smaller point from the larger point

• Add the two points together

• Multiply the two points

• Divide the larger point by the smaller point
