Arectangle with the vertices (3, -2), (3, -4), (7, -2), (7, -4) is reflected across the x-axis and the rotated 90 degrees counter clockwise

The new vertices are:

Step-by-step explanation:

The given vertices are

Rule for reflection about x axis is →.

So, →

     →

     →

     →

Now, new vertices after reflection about x axis are .

Rule for 90 degree rotation counter-clockwise is →.

So, →

     →

     →

     →

Therefore, the new rectangle after reflection about x axis and rotated 90 degrees counter-clockwise has the following vertices:

a rotation about point l
