Question

How do you write an equation in standard form for a line passing through (5, –2) and is parallel to x = 4?

Answer 1

The line `x=4` has infinite slope as will any line parallel to it. So our target line cannot be expressed in point slope form or slope intercept form.

It can be expressed by the equation:

`x=5`

since it passes through a point `(5,-2)`,
which has `x` coordinate `5`.
