Question

5. Point E (-5,0) is one of the vertices ofa rectangle. After a dilation of 3 and atranslation of (x +-3, y-1), what are thecoordinates of E''?

Answer 1

The given coordinate is E(-5,0).

The dilation factor is 3.

The translation is (x-3,y-1).

First, we apply the dilation

`(-5,0)\rightarrow(-15,0)`

Then, we translate the point

`(-15,0)\rightarrow(-15-3,0-1)\rightarrow(-18,-1)`

Therefore, the new coordinates are (-18,-1).
