The image of Rectangle PQRS reflected across the y-axis is Rectangle P'Q'R'S'. If the coordinates of the rectangle are P(-10,3), Q(-6,1), R(-2,6), S(-6,5), what will be the coordinates of P'? (-10,-3) (-3,-10) (3,10) (10,3)

Respuesta :

Reflection across the y-axis means that every point in the figure transforms to

[tex](x,y)\rightarrow(-x,y)[/tex]

Therefore, the point P(-10,3 ) will be transformed into

[tex]P(-10,3)\rightarrow P^{\prime}(10,3)\text{.}[/tex]

which is the fourth choice.
