What is the absolute value of Point B labelled on the number line? A number line with point A at coordinate negative 2.2, point B at coordinate negative 1.6, and point C at coordinate 1.2. Drag and drop the answer into the box to match the correct statement. Number Plotted at Point B a. 1/35 b. 1/15 c. -1/35 d. -1/15 PLZ HURRY

Answers

Answer:

The absolute value of Point B labeled on the number line is 1.6.

Step-by-step explanation:

Data provided in the question

In a number line

A coordinates = -2.2

B coordinates = -1.6

And, C coordinates = 1.2

Now we have to determine the absolute value of point B

Here the absolute value means the real number that contains non-negative value

So if we assume the real number be x

So,

We need to find the absolute value of Point B labelled on the number line.

[tex]\vert x \vert= \vert -x\vert = x[/tex]

[tex]\vert - 1.6 \vert = 1.6[/tex]

So, the absolute value of point B is 1.6

Answer: -4

Step-by-step explanation:

Answer:

- 1/4

Step-by-step explanation:

The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).

Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).

= 3 / -12

= - 1/4
