Question

Rectangle RSTU will be dilated with a scale factor of 1/2 to form rectangle R′S′T′U′. Which ordered pair describes the location of R′?
A. (−2, 4)
B. (1, 4)
C. (1, 7)
D. (4, 4)

Can someone explain this to me (where I can understand it?) without giving me the answer? :) Please and Thank You!

Answer 1

Where is rectangle RSTU?

Answer 2

What is the ordered pair for point R?

Answer 3

IDK @jim_thompson5910 I need it ALL explained to me. :):):)

Answer 4

do you visually see point R on the image?

Answer 5

Hint: Dilation (x*1/2, y*1/2)

Answer 6

Dilation is when the size changes but stays the same proportionally, so with what I said just multiply each coordinate by 1/2.

Answer 7

U(2,6)
U' = (2*1/2, 6*1/2)

Does that make sense?

Answer 8

2 x 1/2, 8 x 1/2? I don't see a six... I see an 8...

Answer 9

In my example I was using U

Answer 10

Oh, so would minwe be right?

Answer 11

Answer 15

Yeah so that's your R' coordinates.

Answer 16

(1,4)

Answer 17

I see. :) So B?

Answer 18

Yes
