Question

In which quadrant or on which axis each of the following points lies. Write abscissa and ordinate each of the following:
(i) (3, -4)
(ii) (-3, 5)
(iii) (-10, 0)
(iv) (-2, -7)

Answer 1

(i) $3,-4$

absicca $=3$ ordinate $=-4$

since absicca is possitive and ordinate negative , it lies in $4th$ quadrant

(ii) $-3,5$

absicca $=3$ ordinate $=5$

since absicca is negative and ordinate is positive, it lies in $2nd$ quadrant

(iii) $-10.0$

absicca $=-10$ ordinate $=0$

since the ordinate is $0$, this point lies on the $x-axis$

(iv) $-2,-7$

absicca $=-2$ ordinate $=-7$

since absicca and ordinate , both are negative, this point lies in $4th$ quadrant
