Question

Q. the point M lies in the IV quadrant. the coordinates of point M are
options:
1. (a, b)
2. (-a, b)
3. (a, -b)
4. (-a, -b)

Answer 1

Answer:

answer option is 3. (a, -b)

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The point M lies in the IV quadrant. the coordinates of point M are

1. (a, b)

2. (-a, b)

3. (a, -b)

4. (-a, -b)

EVALUATION

We know that in cartesian coordinate system the Cartesian plane is divided into four quadrants by x axis and y axis

x - coordinate is called abscissa and y coordinate is called ordinate

We get -

• 1st quadrant - Abscissa is positive , Ordinate is positive

• 2nd quadrant - Abscissa is negative , Ordinate is positive

• 3rd quadrant - Abscissa is negative , Ordinate is negative

• 4th quadrant - Abscissa is positive , Ordinate is negative

Now it is given that M lies in the IV quadrant.

So Abscissa is positive , Ordinate is negative

Consequently the point is (a, -b)

FINAL ANSWER

Hence the correct option is 3. (a, -b)
