Which one should I choose

Linear

Step-by-step explanation:

because when graphed it is a straight line that increases by one unit each time, although the line is negative so the coordinates are slightly difficult when doing the math in your head since it goes backward and does not start at (0,0)

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
