Which set of values is a function?

(6,-5)

(7, -3)

(8, -1)

(9, 1)

Step-by-step explanation:

I'm guessing this is what your answer is by the specification of the question. If it's not, I'm sorry.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
