Question

What are the coordinates of D, E and F after a reflection over the Y axis? Plot these points on the grid and label them D E and F

Answer 1

Reflection over y-axis rule:

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

The initial points have the next coordinates:

`\begin{gathered} D(-3,3) \\ \\ E(5,0) \\ \\ F(2,-2) \end{gathered}`

After the reflection over y-axis:

`D(-3,3)\rightarrow D^(\prime)(3,3)`
`E(5,0)\rightarrow E^(\prime)(-5,0)`
`F(2,-2)\rightarrow F^(\prime)(-2,-2)`
