Answer» (i) 3,−4 ABSICCA =3 ordinate =−4 since absicca is possitive and ordinate NEGATIVE , it LIES in 4th quadrant (ii) −3,5absicca =3 ordinate =5 since absicca is negative and ordinate is positive, it lies in 2nd quadrant (iii) −10.0absicca =−10 ordinate =0 since the ordinate is 0, this point lies on the x−axis(IV) −2,−7absicca =−2 ordinate =−7since absicca and ordinate , both are negative, this point lies in 4th quadrant |
