5,1

OpenStudy (amistre64):

so, x=5, and y = 1? are you sure? from your little drawing you might be mixing those up

OpenStudy (anonymous):

Q=5,1 P=-2,1 R=-2,4

OpenStudy (amistre64):

you will need to work on your point reading skills |dw:1386611043636:dw| lets assume that we know that Q = 1,5 in order to scale iit by .5; we simply mutliply it by .5 .5Q = (.5*1 , .5*5)
