Question

A. Write an expression to represent the difference between the two points shown on the number line. B. Find the distance between the two points. The distance is always positive. the dots, of the number line, is on -1.6 and 0.3

Answer 1

Answer:

A. |x-y|

B. 1.9 units

Step-by-step explanation:

A. If two numbers are pointed on the number line and they are x and y, then the expression to represent the difference between those two numbers is  

|x-y| (Answer)

B. Now, there are two points on the number line and they are at -1.6 and 0.3.

Let x = -1.6 and y = 0.3

Therefore, the distance between those two points will be given by

|x-y|

= |-1.6-0.3|

= |-1.9|

= 1.9 units. (Answer)
