Answer:

C. y = -3

Explanation:

Line L is perpendicular to the y-axis, so line L is just a straight horizontally line going from left to right.

This mean that the x-coordinate they gave us is irrelevant since our flat line is going to pass through all possible x-values. The only thing we need to focus on the the y-value.

So we know that the line passes through (__, -3)

the equation y = -3 gives us a horizontal line that passes through (__, -3).

Therefore answer is C.

Answer A and B are wrong because they gave us vertical lines, we want horizontal lines. D and E are wrong because those are diagonal lines, we want flat horizontal lines.
