Question

the diagram shows a vertical number line. what is the position of point X?

Answer 1

As per the question the diagram given is a vertical line.

We are asked to calculate the position of X.

Here the vertical line is divided into many segments.

As per the diagram, it is obvious that the points marked at different positions are separated by four units from each other i.e the distance between two successive marks is 4 units.

The point X is situated at four marks away from 0.

Hence the position of X will be= 4×4 units

                                                    = 16 units

Hence the correct answer of this question is D.

Answer 2

The correct answer is option 4, 16.

Explanation

Each division on the number line represents 4 units. The point X is located 4 divisions above 0, the origin. On this particular number line, 4 divisions represents $4\times 4=16$ units. This means that the point X is located at $y=16$ on the number line.

The correct answer is the 4th option, whose value is 16.
