plot D ( -2 , -3 ) on the graph paper . Also , plot reflections of D in X axis and Y axis .
Answer :
To get reflection of any point in x and y axis , we keep in mind :
1 ) When the mirror line is the x - axis we change each ( x , y ) into ( x , − y ) ,
So we get reflection over x axis D' ( -2 , 3 )
When the mirror line is the y - axis we change each ( x , y ) into ( - x , y )
So we get reflection over y axis D' ( 2 , - 3 )
Now we show them on x - y plane , As :
