SOLUTION

TO CHOOSE THE CORRECT OPTION

The Coordinates of point Q are

(a) (3, 3.5)

(b) (3.5, 3)

(c) (-3, 3.5)

(d) (-3, -3.5)

CONCEPT TO BE IMPLEMENTED

We know that in two dimensional geometry the Cartesian plane is divided by coordinate axis in 4 quadrant

1. Quadrant I : Both the x - coordinates and y - coordinates are positive

2. Quadrant II : The x - coordinate is negative and the y - coordinate is positive

3. Quadrant III : Both the x - coordinates and y - coordinates are negative

4. Quadrant IV : The x - coordinate is positive and the y - coordinate is negative

EVALUATION

We have to find the Coordinates of point Q

From the given figure we see that the point lies on 3rd quadrant

Both the x - coordinates and y - coordinates will be negative

Now we observe that ,

Distance of Q from x axis = 3.5 unit

Distance of Q from y axis = 3 unit

So we have

Abscissa = - 3

Ordinate = - 3.5

Hence the required Coordinates of point Q is ( - 3 , - 3.5)

FINAL ANSWER

Hence the correct option is (d) ( - 3, - 3.5)
