Evaluate the following expression: 3(1,-1) - (4,-2).

This is a type of matrix notation.  You would multiply both the x and y coordinates by 3 first and then subtract the corresponding x and y-coordinates in that second point to come up with an answer that is in (x, y) format.

For new questions, you do better by putting them in a new post, but since you already posted it here:

Add the 2 "x" entries to get a new "x".  Do the same with the "y" to get a new "y".

Answer will be in form (x, y)

If you have a new question after this, new post.
