Question

Is PS a vertical line, a horizontal line, or neither?

P (-1,0), S (-1,7)

Answer 1

Given:

The two points are P (-1,0) and S (-1,7).

To find:

Whether the line PS is vertical, horizontal or neither.

Solution:

We have, two points P (-1,0) and S (-1,7).

Slope of the line PS is:

`m=(y_2-y_1)/(x_2-x_1)`

`m=(7-0)/(-1-(-1))`

`m=(7)/(0)`

`m=\infty`

We know that the slope of a vertical line is
`\infty`.

Since the slope of the line PS is
`\infty`, therefore PS is a vertical line.
