Answer:

The point R halfway between the integers on the number line is -5.5

Step-by-step explanation:

Topic: Number Line Representation

Given;

2 integers whose values are -6 and -5

Point R which is half way between the two digits

Let x represent -6

Let y represent -5

So, x = -6

and y = -5

To get point R, we have to calculate the mean or average of these two integers.

Mean is calculated using the following formula

[tex]Mean = \frac{(x_{1} + x_{2} + x_{3} + ..... + x_{n})}{n}[/tex]

Where n is the number of variables

In this case, n = 2.

So,

 [tex]Mean = \frac{x_{1} + x_{2}}{2}[/tex]

Where [tex]x_{1} and x_{2}[/tex] are the first and second data.

So, we can say that

[tex]R = \frac{x + y}{2}[/tex]

By Substitution

[tex]R = \frac{-5 + (-6)}{2}[/tex]

[tex]R = \frac{-5 -6}{2}[/tex]

[tex]R = \frac{-11}{2}[/tex]

[tex]R = -5.5[/tex]

Hence, the point R halfway between the integers on the number line is -5.5
