1.

(4,-1) (-3,2)(0,1/2)(7/20,-3/4)

Answer»

(i) Since, x-coordinate of point is 4 which is positive and y-coordinate of point is -1 which is negative.

And we know that if x-coordinate of a point is positive and y-coordinate of that point is negative then that point lies in IV quadrant.

∴ (4, -1) lies is 4th quadrant.

(ii) (-3, 2) lies in 2nd quadrant.

Reason :- Abscissa = negative and ordinate = positive

Then point lies in 2nd quadrant.

(iii) (0, 1/2) lies on positive y-axis.

Reason :- The equation of y-axis is x=0.

i.e. if abscissa is 0 then point lies on y-axis.

(iv) (7/20, -3/4) lies in 4th quadrant.

Reason :- Abscissa = positive and ordinate = negative

Then point lies in 4th quadrant.
