what are the choices

anonymous · Answer

J'(4, -1)
K,(-4, -1)
K'(1, 4)
J'(-4, -1)

ivettef365 · Answer

reflection over the y-axis is (x,y) -> (-x,y)

anonymous · Answer

Watchu mean by that?!? Like yeah I got the first part

Are you sure the points on the question are correct, because I don't see any match?

anonymous · Answer

It was 
J'(4,-1)
K'(-1,-4)
K'(1,4)
J'(-4,-1)

anonymous · Answer

Buhhh thanks

ivettef365 · Answer

ok now makes sense you have points as follows:
  (x,y)  - >  (-x,y)
 J(4,1)         (-4,1)     

and for K
K(1,-4)       (-1,-4)
