Solution 1
Since is a rectangle with two sides on the axes, then its sides are horizontal and vertical. Since is horizontal, the -coordinate of is the same as the -coordinate of , which is 3. Since is vertical, the -coordinate of is the same as the -coordinate of , which is 5. Therefore, the coordinates of are .
