Choose the correct alternative answer for the following quesiton.
Which of the points P ( -1,1), Q (3,- 4), R(1 , -1), S ( -2, - 3), T (- 4,4) lie in the fourth quadrant ?
P and T
Q and R
P and R
The point whose x co-ordinate is positive and y co-ordinate is negative lie in the fourth quadrant.
Thus, the points Q(3, −4) and R(1, −1) lie in the fourth quadrant.
