Because numerical expressions can only contain numbers, expressions containing variables (such as x or y) cannot be considered numerical expressions. When given a verbal or written word problem, it is important to be able to translate the words to a numerical expression so you can solve the problem.

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
