\(\overrightarrowX"OX\) and also \(\overrightarrowY"OY\) represent the co-ordinate axes. The beam \(\overrightarrowOX\) istaken as optimistic x-axis. So, any type of distance along \(\overrightarrowOX\) will certainly be taken together positiveand the beam \(\overrightarrowOX"\) is bring away as an unfavorable x-axis. So, any type of distance relocate along \(\overrightarrowOX"\)will it is in taken as negative.

You are watching: In which quadrants is the ordinate positive?

Similarly, beam \(\overrightarrowOY\) bring away as hopeful y-axis. So, the distancemoved follow me \(\overrightarrowOY\) will certainly be taken together positive and \(\overrightarrowOY"\) is taken as an adverse y-axis.So, the distance moved along \(\overrightarrowOY"\) will certainly be taken together negative.

| The graph will help us tounderstand the convention that the indicators of coordinates. (i) The co-ordinates of any suggest lies in the first quadranthave both the abscissa and ordinate are confident i.e. (+, +).
