A small town is represented on a graph in the coordinate plane. The coordinates of the post office are ( 2,3) which other building is in the same quadrant

Without additional information about the graph or the town's buildings, we cannot determine which other building is in the same quadrant as the post office. A quadrant is one of the four sections formed by the x-axis and y-axis on the coordinate plane. Therefore, any building with both coordinates (x,y) that are either both positive or both negative will be in the same quadrant as the post office.
