Answer:

and
.
Explanation:
The given point is
.
If we want to use a point to create a line with an undefined slope through
, then that point must have the same x-coordinates as the given point.
Since the given point,
has an x-coordinate of
, we check all the points that have an x-coordinate of -3.
The correct answers are;

and
.
These point will make the slope undefined, because it will result in division by zero.
