Step - 1 : Apply properties of y axis . {\textbf{Step - 1 : Apply properties of y axis}}{\text{.}} Step - 1 : Apply properties of y axis .
We know that any point, suppose ( x , y ) on Y axis will have x = 0 . {\text{We know that any point, suppose }}\left( {{x,y}} \right){\text{ on Y axis will have }x = 0}{\text{. }} We know that any point, suppose ( x , y ) on Y axis will have x = 0 .
hence, any point on Y axis will be in the form of ( 0 , y ) . {\text{hence, any point on Y axis will be in the form of }}\left( {0,{y}} \right). hence, any point on Y axis will be in the form of ( 0 , y ) .
Step - 2 : Determine the point . {\textbf{Step - 2 : Determine the point}}{\text{.}} Step - 2 : Determine the point .
So given that the ordinate is 4. {\text{So given that the ordinate is 4}}{\text{.}} So given that the ordinate is 4 .
To be on Y axis it must be of form ( 0 , y ) . {\text{To be on Y axis it must be of form }}\left( {0,{y}} \right). To be on Y axis it must be of form ( 0 , y ) .
So simply the point will be ( 0 , 4 ) {\text{So simply the point will be }}\left( {0,4} \right) So simply the point will be ( 0 , 4 )
Hence, the point with ordinate 4 and on Y axis is ( 0 , 4 ) . {\textbf{Hence, the point with ordinate 4 and on Y axis is }} \mathbf{ \left({0,4} \right).} Hence, the point with ordinate 4 and on Y axis is ( 0 , 4 ) .
