Question

Which point is a reflection of point $A$ over the y-axis?

• A. $C$
• B. $D$
• C. $E$
• D. $G$

Answer 1

The correct option is B $D$

The graph is symmetric(reflection) w.r.t to the $y$-axis i.e. $x=0$ , If $(x,y)$ is a point on the graph ,then $(-x,y)$ is also a point on the graph .

In the given figure ,point $A$ is situated at $(-4,3)$ ,if the graph is symmetric about $y$-axis ,then point $A^{{}^{\prime }}$ must be situated at $(4,3)$

in the given graph point $D$ is situated at $(4,3)$ ,this implies point $D$ is a reflection of point $A$ over the $y$-axis
