Answer:
Step-by-step explanation:

Step-by-step explanation:
Vertical lines take the form of and horizontal lines take the form of

So the line (we got -12 from the coordinate that was given to us on the question prompt) is a vertical line that passes through virtually all possible y values (from positive infinity to negative infinity, or vice-versa) which means that the question prompt having given us the y value was negligible.
Good luck!
