Question

How do you write an equation of a line given P(3, -4), slope is undefined?

Answer 1

See the entire solution explanation below:

Explanation:

A line with an undefined slope is a vertical line.

A vertical line will always have the same value of `x` for every value of `y`.

The value of `x` in point `P` given in the problem is `3`

Therefore, the equation of the line is:

`x = 3`
