\"\"

\

a.

\

The ordered pair is \"\".

\

Step 1: Start at the origin.

\

Step 2: Since the \"\"- coordinates of point \"\" is \"\", move \"\" units to the right.

\

Step 3: Since \"\"- coordinate is \"\", move \"\" units to up.

\

b.

\

The ordered pair is \"\".

\

Step 1: Start at the origin.

\

Step 2: Since the \"\"- coordinates of point \"\" is \"\", move \"\" units to the right.

\

Step 3: Since \"\"- coordinate is \"\", move \"\" units to up.

\

Therefore, the point \"\" interchanged \"\" and \"\" coordinates of point \"\".

\

\"\"

\

The point \"\" interchanged \"\" and \"\" coordinates of point \"\".
