To determine how deep the swimmer's dive was, we need to look at the vertical position indicated by the coordinates of the lowest point of the dive, which is given as (5, -4).
In this context:
- The x-coordinate (5) represents the horizontal distance from the pool's front wall.
- The y-coordinate (-4) represents the vertical position of the swimmer. A negative value indicates a position below the water level (assuming the surface of the water is at y = 0).
Since the lowest point of the swimmer's dive is (5, -4), this indicates that the swimmer is 4 units below the surface of the water.
Thus, the depth of the swimmer’s dive is 4 units.
