Which two ordered pairs \( (r, \theta) \) plot a point in the same location as the point at \( (7,3 \pi / 2) \) ? (Hint: this point is on the vertical axes below the horizontal axis) \( \square(-7,3 \pi / 2) \) \( \square(7,-3 \pi / 2) \) \( \square(7,-\pi / 2) \) \( \square(-7,-\pi / 2) \) \( \square(-7, \pi / 2) \)
