The point lies in quadrant IV.

The form of point lies in quadrant IV is and example of point is .

Therefore a is positive and b is negative.

The point .

In the point, x - coordinate is negative and y - coordinate is positive.

The x - coordinate is negative and y - coordinate is positive in quadrant II.

The form of point lies in quadrant II is and example of point is .

The point . Here is positive, since b is negative.

In the point, x - coordinate is positive and y - coordinate is positive.

The x - coordinate is positive and y - coordinate is positive in quadrant I.

The form of point lies in quadrant I is and example of point is .

The point . Here is positive, since b is negative.

The x - coordinate is positive and y - coordinate is negative in quadrant IV.

The form of point lies in quadrant IV is and example of point is .

The point lies in quadrant II, the point lies in quadrant I and lies in quadrant IV.
