Question

Please help asap!! translation: ( , ). scale factor : ?

Answer 1

it's a dilation of 3.5

Explanation:

14/4=3.5

7/2=3.5

(x , y) → (14/4 , 7/2) or (3.5 , 3.5)

Answer 2

1. Translation is (x - 6, y - 1)

2. Scale factor is 3.5

Explanation:

Let's do translation first, then scale factor

1. Let's pick point R ( 6, 1), point R' (0,0)

We see that the x decrease by 6, and the y decrease by 1

So the translate is (x - 6 , y - 1)

2. Let's count the distance from Q to S; it is 4 squares. Now let's count the distance from Q' to S' is 14. Take 14 divided by 4 = 3.5. So, the scale factor is 3.5
