Which set of ordered pairs represents a function? {(-2,5), (6,9), (8, –4), (8, 7)}
{(-1,4), (-5, -2), (6,1),(-2,-2)}
{(-5, -6), (-5,3), (-7, -8), (-1, -9)}
{(-8, -4), (-8, –5), (-6, -1),(3,6)}

Please help

B. the second one

Step-by-step explanation:

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

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
