Understanding Segment Lengths

The video tutorial explains how to calculate the length of line segments on a number line. It begins with segment BD, showing different methods to find the distance between points B and D. The tutorial then covers calculating the distance between points 1 and 4, and finally, it demonstrates finding the length of segment AD. The video emphasizes understanding the concept of distance on a number line and provides step-by-step examples for clarity.

What is the length of segment BD if point B is at -2 and point D is at 5?

• 3

• 5

• 9

• 7

Which of the following is a correct method to find the distance between two points on a number line?

• Subtract the smaller coordinate from the larger one

• Multiply the coordinates of the points

• Add the coordinates of the points

• Divide the larger coordinate by the smaller one

If you start at -2 and count to 5, how many steps do you take?

• 6

• 7

• 5

• 8

What is the distance between points 1 and 4?

• 2

• 5

• 3

• 4

How do you calculate the length of segment AD if A is at -5 and D is at 4?

• Multiply -5 and 4

• Divide 4 by -5

• Subtract -5 from 4

• Add 5 and 4

What is the result of 4 minus negative 5?

• -1

• 0

• 9
