Question 14
If P(-1, 1), Q(3, - 4 ), R(1 - 1), S(- 2, -3) and T(-4, 4) are plotted on the graph paper, then the points(s) in the fourth quadrant is /are:

A) P and T
B) Q and R
C) Only S
D) P and R

Solution

The answer is B.
Point P( -1, 1) x-coordinate is -1 unit and y-coordinate is 1 unit, so it lies in lI quadrant.
Similarly, we can plot all the point Q(3, - 4) R(1, - 1), S( -2 , -3) and R( -4 , 4).

It is clear from the graph that pints R and Q lie in the fourth quadrant.
