16. Quadrant I of the standard (x, y) coordinate plane is shown on a large computer screen. A blinking dot is positioned at (2, 3). The dot makes exactly 2 moves: first, horizontally in the positive x direction for 4 seconds at a speed of 0.5 coordinate units per second; then, vertically in the positive y direction for 2 seconds at the same speed. At what point is the dot located after these 2 moves?
