Hi there!
The correct answer is option B
--------------------------------------------
Since x = -4 is a vertical line(perpendicular to horizontal), so there is no y-intercept and the slope is undefined.
"A vertical line has undefined slope because all points on the line have the same x-coordinate.
So, the slope is undefined and we also don't have the y - intercept.

Best of luck with your studies!
