Answer 2

Bonjour! :D

Answer 3

@IMStuck Aloha, welcome back dear :))

Answer 4

What is point K? and K ' ?

Answer 5

I'm using sides JK and J'K' as my two sides of comparison. Side JK has a length of 2 units, can you tell how many units long J'K' is?

Answer 6

I was at work for several hours...but I couldn't wait to get back on here and do more math stuff! ; )

Answer 7

point K is 2, 4 and K' is 4,8 ?
-I'm glad :)

Answer 8

the x coordinate of K is 2
the x coordinate of K' is 4


the y coordinate of K is 4
the y coordinate of K' is 8


what's the rule to go from K to K ' ?

Answer 9

jim_thompson5910 is showing you how to relate the points to the origin to find out the scale change. I used the length of the sides to find the scale change, but they are both going to come out the same. What did you do the 2 to make it a 4? What did you do to the 4 to make it an 8? Keep in mind that you have to do the same thing to both the 2 andd the 4. You can't add to one an then multiply to the other. What is the rule?

Answer 10

2
and 4

Answer 11

You have to do the same thing to the 4 that you do to the 2. That is to...what? Are you getting this or do you need a clue as to what I'm asking.

Answer 12

no, I'm confused on what you're asking

Answer 13

Like 2 + 2 = 4, but 4 + 2 does not equal 8. so you know you are not just adding 2 to both.

Answer 14

You are actually multiplying the 2 by a 2, and the 4 by a 2. 2 * 2 = 4, and 4 * 2 = 8. So your scale factor is 2.

Answer 15

no we're multiplying by 2

Answer 16

Yes! Good! Very good! Yay for you!

Answer 17

... @IMStuck so it's B?

Answer 18
