I don't know if it's just me but this girl who keeps answering questions saying "couldn't attached it here but answer in the link" or something stu. pid like that really needs to stop. Some people come on here because they actually need help and those links just lead to viruses so if it's you doing it you seriously need to stop. This is her profile pic if you know who im talking about-

I know her at molecular level because I've reported her thousands of times.

step-by-step explanation:

c

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
