Write the equation of a line that goes through point (4,0) and has an undefined slope
x=4
x=0
y=4
y=0

The equation of the line with the following characteristics is: x = 4.

------------

Traditionally, the equation of a line is given by:

However, if the slope is undefined, there is a vertical line, given by equation:

In this question, it goes through point (4,0), that is, , and the equation if:

.

A similar problem is given at link

Step-by-step explanation:

A line with undefined slope is a vertical line.

An equation of a vertical line: x = a  (a - real number).

Each point on a line x = a has coordinates (a, b)  (b - any real number).

We have the point (4, 0) → x = 4
