Final answer:
The points are located in different quadrants: A (5,175) in quadrant II, B (-5,-8) in quadrant III, C (23) does not have a y coordinate, D (2,-3.5) in quadrant IV, and E (4.5,3.75) in quadrant I.
Step-by-step explanation:
The quadrant in which each point is located can be determined by the signs of the x and y coordinates.
- Point A (5,175) is located in quadrant II because the x coordinate is positive and the y coordinate is positive.
- Point B (-5,-8) is located in quadrant III because the x coordinate is negative and the y coordinate is negative.
- Point C (23) does not have a y coordinate and is therefore not located in any quadrant.
- Point D (2,-3.5) is located in quadrant IV because the x coordinate is positive and the y coordinate is negative.
- Point E (4.5,3.75) is located in quadrant I because both the x and y coordinates are positive.
