Q2 of 17 Page 116

Write the abscissae and ordinates of the following points.

i) (4, -8)


ii) (-5, 3)


iii) (0, 0)


iv) (5, 0)


v) (0, -8)


Note : Plural of abscissa is abscissae.

As we know, the abscissa of a point is its x co-odinate and ordinate of a point is its y co-ordinate {if a point≡(x,y)}.


So,


(i) For the point (4,-8) :


abscissa : 4


ordinate : -8


(ii) For the point (-5,3) :


abscissa : -5


ordinate : 3


(iii) For the point (0,0) :


abscissa : 0


ordinate : 0


(iv) For the point (5,0) :


abscissa : 5


ordinate : 0


(v) For the point (0,-8) :


abscissa : 0


ordinate : -8
