Answer asap! the equation of a line is y = 2x + 3. what is the equation of the line that is parallel to the first line and passes through (2, –1)?
a. 4x-2y=-6
b. y = 2x-5
c. y=3x+4
d. 2x+y=-1

i can try and you the very best that i can.

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
