Final answer:
The coordinates of point P, which is 2 units left and 4.5 units down on a Cartesian coordinate plane, are (-2, -4.5).
Step-by-step explanation:
The question involves finding the coordinates of a point on a Cartesian coordinate plane. Since point P is said to be moving 2 units to the left, this indicates a negative movement along the x-axis. Similarly, moving 4.5 units down indicates a negative movement along the y-axis.
Therefore, we can denote the movement to the left as -2 and the movement downward as -4.5, giving us the coordinates of point P as (-2, -4.5). The correct answer to the question is Option B, which is (Negative 2, Negative 4.5).
