Math Problem Statement
Solution
Let's break down the problem and solve it step by step.
We have two points:
The transformations that will be applied are as follows:
-
Translation by vector , meaning we add 2 to the x-coordinates and subtract 3 from the y-coordinates of both points.
For point :
For point :
-
Reflection over the line . To reflect a point over this line, we switch the coordinates and change their signs. In other words, the reflection of a point over the line is .
For point :
For point :
-
Rotation by 90° clockwise. A 90° clockwise rotation transforms a point into .
For point :
For point :
So, after performing all the transformations, the final coordinates of and are:
Thus, the correct answer is D.
