Ineed and explain how u got the answer

C

Step-by-step explanation:

What you want to do here is take your point (4, 12) and plug it into all of those equations. If the point is on the line, you'll get something like 12 = 12 or 4 = 4 (an expression that is true!). If the point isn't on the line, you'll get something that doesn't make sense, like 4 = 6 (which is not true).

A. y = (3/4)x + 9 ... plug in (4, 12)

12 = (3/4)4 + 9 ... simplify

12 = 12 ... so (4, 12) is on this line.

B. y = (- 1/2)x + 14 ... plug in (4, 12)

12 = (-1/2)4 + 14 ... simplify

12 = 12

C. y = (1/2)x + 8 ... plug in

12 = (1/2)4 + 8 ... simplify

12 = 10 ... this is NOT true, so C does not contain the point.

D. y = -2x + 20 ... we'll just check it to be sure

12 = -2(4) + 20

12 = 12

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
