Question 19 (1 point) (03.06 LC)
Choose the equation below that represents the line passing through the point (1,-4) with a slope of
1
2
(1 point)
O a
y - 4= -(x - 1)
4=
Oь
y + 4 = 2(x - 1)
Ос
y+4=(-1)
Od
y - 4 = 2(x + 1)

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
