2. Relevant equations

3. The attempt at a solution

So would these be the points?

(-4_{1},5_{1}),(-2_{2},6_{2}),(2_{3},6_{3}),(4_{4},2_{4})

I'm not too sure how to evaluate the sigmas because it shows n as being the subscript up above in the directions but in the problem it shows i as being the subscript, and I don't understand how i can equal 1. When clearly the subscript is not always 1.
