Find the co – ordinates of the picture of A $\left( -5,4 \right)$ after reflection within the line.(i) y $=0$(ii) y = 4
Find the co – ordinates of the picture of A $\left( -5,4 \right)$ after reflection within the line.(i) y $=0$(ii) y = 4

Co – ordinates of the image$=(-5,(2\times 0)-4)$

$=(-5,(0-4))$

$=\left( -5,-4 \right)$

Co – ordinates of the picture  $=\left( -5,\left( 2\times 4 \right)-4 \right)$

$=\left( -5,\left( 8-4 \right) \right)$

$=\left( -5,4 \right)$
