we know that

The slope of the lines parallel to the y-axis or vertical lines is undefined and the slope of the lines parallel to the x-axis or horizontal lines  is equal to zero

In this problem we have

x=4

This is the equation of a vertical line parallel to the y-axis

the slope is undefined

therefore

<u>the answer is the option</u>

The line is vertical. The slope is undefined

Answer:  The correct option is (B)  The line is vertical. The slope is undefined.

Step-by-step explanation:  We given to check whether the line  x = 4 is horizontal or vertical.

Also, we are to find the slope of the line and select the best option.

The given line is

x=4.

Since the straight line of the form x = k, a constant is parallel to Y-axis. Since Y-axis is the vertical axis, so, the line must be vertical.

Therefore, the line x = 4 is also vertical.

Now, (4, 0) and (4, 1) are any two points on the given line.

So, the slope of the line will be

S=\dfrac{1-0}{4-4}=\dfrac{1}{0},

which is undefined.

Therefore, the slope of the given line is undefined.

Thus, the given line is vertical and its slope is undefined.

Option (B) is correct.
