Question

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 ant T
• B. Q and R
• C. Only S
• D. P and R

Answer 1

The correct option is B

Q and R

In 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 T( -4 , 4 ).

It is clear from the graph that the points R and Q lies in fourth quadrant.
