This line would be considered undefined. You could write the line as x=-3. However, this is not considered slope intercept form.

Explanation:

y=mx+b requires a slope. The slope for a vertical line would be greater than infinite in a way, so it is not possible to write an equation in y=mx+b form that is vertical. If it was a horizontal line then you could write it as y = 7.
