The pair of points is on the graph of an inverse variation. Find the missing value. (1.6, 6) and (8, y) 0.03 30 1.2 0.83
ZanzabumX [31]
One may note that (1.6 , 6)  is just another way to say x = 1.6 when y = 6.

and that (8 , y) is another way to say x = 8 and y is who knows.

\bf \qquad \qquad \textit{inverse proportional variation}\\\\&#10;\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby &#10;\begin{array}{llll}&#10;k=constant\ of\\&#10;\qquad  variation&#10;\end{array}\\\\&#10;-------------------------------

\bf \textit{we know that }&#10;\begin{cases}&#10;x=1.6\\&#10;y=6&#10;\end{cases}\implies 6=\cfrac{k}{1.6}\implies 6(1.6)=k\implies 9.6=k&#10;\\\\\\&#10;\qquad therefore\qquad \boxed{y=\cfrac{9.6}{x}}&#10;\\\\\\&#10;\textit{when x = 8, what is \underline{y}?}\qquad y=\cfrac{9.6}{8}
