Final answer:
The points (5, 4.5), (1.5, 3), and (3, 1.5) all lie in Quadrant I.
Step-by-step explanation:
To determine the quadrant in which the points (5, 4.5), (1.5, 3), and (3, 1.5) lie, we need to understand the concept of quadrants in the coordinate plane. The x-coordinate represents the horizontal position and the y-coordinate represents the vertical position of a point. In Quadrant I, both the x-coordinate and the y-coordinate are positive, in Quadrant II the x-coordinate is negative and the y-coordinate is positive, in Quadrant III both the x-coordinate and y-coordinate are negative, and in Quadrant IV the x-coordinate is positive and the y-coordinate is negative.
Let's analyze each point:
- (5, 4.5): Both the x-coordinate and y-coordinate are positive, so this point lies in Quadrant I.
- (1.5, 3): Both the x-coordinate and y-coordinate are positive, so this point also lies in Quadrant I.
- (3, 1.5): Both the x-coordinate and y-coordinate are positive, so this point also lies in Quadrant I.
Therefore, all three points (5, 4.5), (1.5, 3), and (3, 1.5) lie in Quadrant I.
