Question

Which are the coordinates of the transformed point?

(4, -4); vertical compression of 1/2

Answer 1

Do u want vertical ???

Answer 2

Yes, vertical compression

Answer 3

For what ?
On what means ?

Answer 4

If i had a point on a graph, at (4, -4), to make a vertical compression, would I go up 1 unit and then to the right 2 units to get my new "transformed" point?

Answer 5

These are the answer choices. My lessons didn't teach much about "compressions" that is why I am asking. And when i get to my test, almost everything is about "Compressions". This is the reason I am asking.

Which are the coordinates of the transformed point?

(4, -4); vertical compression of 1/2

a. (2, 2)
b. (-2, 2)
c. (2, -2)
d. (4, -2)

Answer 6

@phi can you help?

Answer 7

I would think vertical compression only affects the vertical (the y ) part
so the answer should have x stay 4

Answer 8

compress sounds like "squeeze" or make smaller.
so compress by 1/2 means make the y value 1/2 as big: 1/2 * -4 = -2

Answer 9

So the answer would be B?

Answer 10

re-read what I posted

Answer 11

Oh!, so the -2 = y?

Answer 12

and my very first post ?

Answer 13

so the new coordinate would be (4, -2)??

Answer 14

that's what I think.

Answer 15

Yay!
now i have one more, I think i got the answer for it, but can you check my work?

Answer 16

did you post it ?
