Question

How do you find the equation of a line that Contains (-2, -7) and is parallel to x=4?

Answer 1

`x=-2`

Explanation:

The line `x=4` is vertical, so any line parallel to it will be vertical too.

The equation of a vertical line is `x=c` for some constant `c`.

In our case, this must be satisfied by the point `(-2, -7)`, which has `x=-2`, hence the equation of our desired line is `x=-2`.
