@sourwing help me please

Answer 3

I think what is asking you to switch your x with y variables and then take the negative of x (which would be y now)

Answer 4

This is just a guess on my part I'm not familure with this notation

Answer 5

so,
P(6, -(-8)), Q(-3, -(1)), R(-3, -(-3))

Answer 6

Does that help?

Answer 7

It is my best guess at the notation, you probably have reading materials that cover this though

Answer 8

You probably already know this but,

-(-1) = +1
-(+1) = -1
+(+1) = +1
+(-1) = -1

or,

++ = +
-- = +
+- = -
