Question

What is the equation of the line that passes through the point (8,−3) and has an undefined slope?

Answer 1

Answer: x= 8

Explanation:

It is a vertical line that passes through point 8 on the x axis.

Answer 2

`x = 8`

Explanation:

Recall that horizontal lines have a slope of zero, while vertical lines have an undefined slope.

Therefore, the line must be vertical.

And since it is vertical, we will only need to consider the x-coordinate of our point.

The x-coordinate of (8, -3) is 8.

Hence, the equation of the line that passes through (8, -3) with an undefined slope is:

`x = 8`
