Work Step by Step
a) (-2,-10) is in quadrant III because both values are negative
b) (4,8) is in quadrant I because both values are positive
c) (-9,12) is in quadrant II because the x value is negative but y value is positive
d) (3,-9) is in quadrant IV because the x value is positive and the y value is negative
e) (0,-8) since the point is a y intercept (located on the y axis) it is not considered to be in a quadrant
f) (2.3,0) the point is an x intercept (on the x axis) so it is not considered to be in a quadrant
