Complete the following table: Point Reflection in x -axis y -axis origin - 3 , 7

We know that, When a point ( x , y ) is reflected in x -axis, the sign of its second component (ordinate) changes, i.e., the sign of y changes and so the image of ( x , y ) in x -axis is ( x , - y ) . When a point ( x , y ) is reflected in y -axis, the sign of its first component (abscissa) changes, i.e., the sign of x changes and so the image of ( x , y ) in y -axis is ( - x , y ) . When a point ( x , y ) is reflected in origin, the signs of both of its components changes. i.e., the image of p ( x , y ) in y -axis is p ' ( - x , y ) . It is given that, a point - 3 , 7 is reflection in x -axis is - 3 , - 7 , reflection in y -axis is 3 , 7 and the reflection of origin is 3 , - 7 . Hence, the required answer is as shown below. Point Reflection in x -axis y -axis origin - 3 , 7 - 3 , - 7 3 , 7 3 , - 7
