Question

How do you find the slope and intercept of `x + 1 = 0`?

Answer 1

`x+1=0` is the equation of a vertical line.

Explanation:

There is no definition of the slope of a vertical line.

The line has `x` intercept `-1`. It does not have a `y` intercept.

It can be written `x=-1`, but it cannot by written in slope intercept form (`y=mx+b`) because it does not have a slope and it does not have a `y` intercept.
