MCQ
The reflection of the point $P(-4,5)$ in $y$-axis has the coordinates
- A$(-4,-5)$
- B$(4,5)$
- C$(4,-5)$
- D$(5,-4)$

Answer
B.(4,5)
The reflection of point $P(-4,5)$ is its mirror image in line mirror along $y$-axis. So, $P$ and $Q$ are equidistant from $y$-axis on its opposite sides. So, $x$-coordinate of $Q$ is 4 . Also, $P$ and $Q$ have same $y$-coordinates as $P Q$ is perpendicular to $y$-axis. Hence, the coordinates of $Q$ are $(4,5)$.
