Question

What are the coordinates of the vertices of quadrilateral W, L, H and D? The 1st part of instructions are in the pic below.

Answer 1

Since we have a reflection over the y-axis, we have that

`(x,y)\rightarrow(-x,y)`

Therefore, the new coordinates are:

`\begin{gathered} W^(\prime)(-6,4) \\ L^(\prime)(-6,-4) \\ H^(\prime)(2,-6) \\ D^(\prime)(2,3) \end{gathered}`
