The rule for a rotation by 90 about the origin is <span>(x,y)→(−y,x<span>)
so
</span></span><span>(-6,-2) ---> (2, -6)
(-3,1) </span> ---> (-1,-3)<span>
(-1,1) </span> ---> (-1,-1)<span>
(2,-4)</span> ---> (4, 2)
They are all like-terms so you can add 7y+3y which equals 10y. Then subtract 10y-17y and you get a negative number; -7y
