Given A(-3,-1), B(-2,3), C(6,1), and D(5,-3), reflect Quad ABCD over the line y = -x.

A'(_, _)
B'(_, _)
C'(_, _)
D'(_, _)

I'm really bad at math and since we're in quarantine, I can't exactly go to my teacher for help. Hopefully someone here can explain to me what the problem is (what it's asking me) and how I can find the new coordinates. Thank you and have a good day!

Answerthe simplified expression isexplanationthe given expression is,let us deal with the bracket first.the two negatives in the parenthesis will become positive.the expression now becomes,we now expand the parenthesis to get,we group like terms to obtain,this simplifies to,

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
