Answer 1

vertical line will form if the value of x's are the same

Answer 2

now if you know that the requirement for a vertical line to exist, we just need to worry about the units or length.

if you noticed in the illustration I provided, there are 4 in distance in the value of y
from 4 to 7

So this tells us that units of length will be dictated by how far the values of y in the coordinates that have the same x value.

Answer 3

This is a mere intuitive beginning and do not make any use of the distance formula. In fact, any vertical and horizontal line's units or length does not really require the distance formula.

Answer 4

To recap and expand the concept. When the values of the x in the coordinates are the same, you get a vertical line (upward line), and the units (length or distance) are determined by the absolute value of the y from one point to another. Similarly, when the values of the y are the same you get a horizontal line and the units are determined by the absolute values of x.
