OpenStudy (anonymous):

Sorry, I'm no good at this. Better at equations ;P

OpenStudy (anonymous):

Okay. thanks though

OpenStudy (alexalas):

multiply the x and y coords by 4

OpenStudy (anonymous):

so, for each point I just multply them by 4? then what do I do

OpenStudy (alexalas):

do you have to graph it?

OpenStudy (anonymous):

No, but I have to explain how I got the answer

OpenStudy (anonymous):

Not explain, just show all of my work

OpenStudy (alexalas):

find the coords and multiply them on paper so C is (x,y) so you would write (x*4,y*4)

OpenStudy (anonymous):

x is 2 and y is 3?

OpenStudy (anonymous):

would it be (2*4, 3*y)

OpenStudy (anonymous):

3*4)

OpenStudy (alexalas):

yes

OpenStudy (anonymous):

let me calculate each point

OpenStudy (anonymous):

Is it 12, 16?

OpenStudy (alexalas):

2*4=8 and 3*4=12

OpenStudy (alexalas):

a=(-3,1) b=(4,-3) c=(2,3) d=(-1,4) so dilated by 4 a=(-12,4) b=(16,-12) c=(8,12) d=(-4,16)

OpenStudy (anonymous):

Okay, is that the answerz?

OpenStudy (alexalas):

yes

OpenStudy (anonymous):

Oh, that makes sense.

OpenStudy (alexalas):

so you good?

OpenStudy (anonymous):

Yes. Thank you

OpenStudy (alexalas):
