Chapter 1: Q19. (page 31)

Refer to a number line that is not pictured here. PointAhas coordinate 2 and pointBhas coordinate 5.

What is the coordinate of a point that is on AB鈫�and is 4 units fromB?

Short Answer

Expert verified

The required coordinate is 9.

Step by step solution

01

Step 1. Make the number line.

Make a number line that consists of two points A and B according to the provided information and a number 0 between A andB

02

Step 2. Observe the number line.

The mentioned point is 4 units far from the point B therefore to reach the required point the gap should be added to the coordinate of B.

03

Step 3. Make the conclusion.

If the addition between the coordinate of B and 4 performed, then it will return a value 9 which is the required coordinate.
