Exercise 4 Page 173

Which part of the coordinate plane is Quadrant IV?

E(3,-3)

Practice makes perfect

Quadrant IV is the region that contains points with positive x-coordinates and negative y-coordinates. Only point E(3,-3) lies within this region.

Since 0 is neither positive nor negative, point D(2,0) is not in any quadrant because it lies on the axis.
