Best ResponseYou've already chosen the best response.0Ah, that was my first assumption, but I second guessed myself.

Best ResponseYou've already chosen the best response.1and for the other its A too

Best ResponseYou've already chosen the best response.1we use the x axis matrix \[\left[\begin{matrix}1 & 0 \\ 0 & 1\end{matrix}\right]\]times it by each vertex to find solution of its it image

Best ResponseYou've already chosen the best response.1the 270 degree matrix \[\left[\begin{matrix}0 & 1 \\ 1 & 0\end{matrix}\right]\]we do the same here too

Best ResponseYou've already chosen the best response.0Thanks! I really appreciate your explanations because matrices have been giving me such a hard time.

Best ResponseYou've already chosen the best response.1example with vertices V(8,4) and we want its image that was revolve 270 degree we multiply that by its matrix \[\left[\begin{matrix}0 & 1 \\ 1 & 0\end{matrix}\right]*\left(\begin{matrix}8 \\ 4\end{matrix}\right)\]\[\left(\begin{matrix}0*8+(1)*4 \\ (1)*8+0*4\end{matrix}\right)\]we get \[\left(\begin{matrix}4 \\ 8\end{matrix}\right)\]as the image of V

Best ResponseYou've already chosen the best response.0Ah, I see. Do you think you can help with scale factor with matrices as well?

Best ResponseYou've already chosen the best response.0So this is my question. http://prntscr.com/8g302o I got A, but I was just guessing since the others didn't look right, but the points aren't exact, so it's kind of confusing.

Best ResponseYou've already chosen the best response.0Actually I think it's this one! http://prntscr.com/8g30iv

Best ResponseYou've already chosen the best response.1ok so w(1, 2).. z(2, 4)...x(5,5)...y(5,3)

Best ResponseYou've already chosen the best response.1its images is being multiple by 3

Best ResponseYou've already chosen the best response.1so for image w we get 3(1, 2) which give (3, 6)
