Which ordered pairs satisfies an inverse variation

Question

F. (6,3) (8,4).        H. (4,-1) (-5,10).             G. (2,-3) (4,5) .       J.(2,6) (-3,-4)     

Answer 1

For inverse variation: y=k/x  so   xy=k.

(6,3) (8,4)     -->  xy=18 and  xy=32       no

(4,-1) (-5,10) -->  xy=-4  and  xy=-50     no

(2,-3) (4,5)    -->  xy=-6  and  xy=20       no

(2,6) (-3,-4)   -->  xy=12 and  xy=12       yes
