 (-6,2)

(-6,4)

(-4,4)

(-4,5)

(-3,3)

Answer 1

When doing this rotation, former x values get their signs changed but remain as x coordinates (i.e. opposited)

and former y values get their signs changed but remain as y coordinates (also opposited).

 

So former (-4,5) becomes (4,-5).   You can complete your table by following this rule carefully.
