Question

A point P(a,b) is reflected in the Y-axis to P'(-3,1). write down the values of a and b.P'' is the image of P when reflected in the X-axis. Write down the coordinates of P''.P''' is the image of P ehen reflected in the line X=5. write down the coordinates of P'''.

Answer 1

If you are in class 11 and you know about gradient (slope) then it will be easier or else imagine that y axis is your mirror and you get image at same angle and same height
