Start at (0, 0), where the x-axis and y-axis intersect, inside Jefferson High School.
Go 3 units left until you are vertically below Parking Lot B. That means the x-coordinate is -3. Now go up vertically 4 units. The y-coordinate is 4.
The point is (x, y), or in the order of x first followed by y, so it is (-3, 4).
Answer: C. (-3, 4)
