(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. |
