The ordinate and abscissa of a point P are 2 and -9 respectively. The coordinates of point P is
(-9, -2)
(2, -9)
The coordinates of a point are written in the following order: ( abscissa, ordinate).
Hence, for point P, the coordinates are (-9, 2).
Two points P & Q are marked on the number line as shown in the figure. The co-ordinate of Q is 9 and the distance between them is 17 units. The co-ordinate of P is
