Question

If then quadrilateral MATH was reflected over the y-axis, what is the coordinate point of H?

Answer 1

We have that the general rule for a y-axis reflection is:

`r_y(x,y)=(-x,y)`

In this case, the point H is H=(-3,2), then, applying the equation we have:

`\begin{gathered} r_y(-3,2)=(-(-3),2)=(3,2)=H^(\prime) \\ \Rightarrow H^(\prime)=(3,2) \end{gathered}`

therefore, the cooridnate point of H after a y-axis reflection is H'=(3,2)
