OpenStudy (anonymous):

Hey ok so do you know the formulas like an easy way to do it

OpenStudy (anonymous):

So when you are rotating it 90 degrees : it goes from (x,y) into (-y,x)

OpenStudy (anonymous):

so what are your points at ? R: Z: Q: E:

OpenStudy (shaleiah):

(-1,-1) (-1,-1) (-2,3) (-5,1)

OpenStudy (anonymous):

R: (-1,1) Z: (-1,-2) E: (1,-5) Q:( 3,-2)

OpenStudy (anonymous):

those are your points so after u do (x,y) into (-y,x) what would your answer be

OpenStudy (anonymous):

(-1,-1) (2,-1) (5,1) (2,3)

OpenStudy (anonymous):

thats what i got

rebeccaxhawaii (rebeccaxhawaii):

mm

OpenStudy (anonymous):

i am confused why do u have 2 grpahs ?

OpenStudy (shaleiah):

:) The instructor told me to include the preimage and the image.

OpenStudy (dinamix):

yes ?

OpenStudy (shaleiah):

Could you check my graph?

OpenStudy (anonymous):

which one is ur image and preimage u need to have like said which one is which?

OpenStudy (shaleiah):

Your right

OpenStudy (shaleiah):

ok thanks

OpenStudy (shaleiah):

@Plasmataco

OpenStudy (anonymous):

check it again

OpenStudy (anonymous):

R' (-1,-1) Z' (2,-1) E' (5,1) Q' (2,3)

OpenStudy (anonymous):

theses are wrong

OpenStudy (anonymous):

like for R' for example u have it at (-2,-4) its suppose to be at (-1,-1)

OpenStudy (shaleiah):

OpenStudy (shaleiah):

I think I fixed it... what do you think?

OpenStudy (anonymous):

E: (1,-5) Q:( 3,-2) u have it at Q (2,3) E (1,5)

OpenStudy (anonymous):

u see what i am saying ?

OpenStudy (shaleiah):

yes..

OpenStudy (anonymous):

where are u graphing this ?

OpenStudy (shaleiah):

https://app.geogebra.org/#geometry

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

did u fix it ?

OpenStudy (shaleiah):

wait...

OpenStudy (shaleiah):

OpenStudy (shaleiah):

Would you say this is correct?

OpenStudy (shaleiah):

@surjithayer
