Select the quadrant or axis where each ordered pair is located on a coordinate plane. Quadrant I
Quadrant II
Quadrant III
Quadrant IV
xxx-axis
yyy-axis
(8,3)(8,3)left parenthesis, 8, comma, 3, right parenthesis
(9,-2)(9,−2)left parenthesis, 9, comma, minus, 2, right parenthesis
(-3.5,-6)(−3.5,−6)left parenthesis, minus, 3, point, 5, comma, minus, 6, right parenthesis

(9.5, 0) is in quadrant I. (-4, 7) is in quadrant II. (-1, -8) is in quadrant III.

Step-by-step explanation:

The negative signs say everything (quite literally). If there are no negative signs, it is in quadrant I. If there is one in the x-axis (the first number in an ordered pair), it is in quadrant II. If there are 2 negative signs, it is in quadrant III, and if there is one in the y-axis (the second number in an ordered pair), it is in quadrant IV.
