Question

What is the best description of the translation of pre-image ABC to image A'B'C'? A'B'C'

Answer 1

Answer:

the translation is 4 units at right and 2 units up

Step-by-step explanation:

see the attached figure to better understand the problem

looking at the graph

we have

The coordinates of the pre-image ABC are

A(-1,1),B(2,2),C(1,-1)

The coordinates of the image A'B'C' are

A'(3,3),B'(6,4),C'(5,1)

so

A(-1,1) ---->  A'(3,3)

A(-1,1) ----> A'(-1+a,1+b)

-1+a=3 ---> a=3+1=4

1+b=3 ---> b=3-1=2

The rule of the translation is

(x,y) ----> (x+4,y+2)

That means ----> the translation is 4 units at right and 2 units up
