Question

Can someone check to see if I'm right?

Do the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the table.
xl 1 l 3 l 3 l 7 l
yl 5 l 15 l 20 l 35 l

direct variation; y= 1/5x
inverse variation; xy= 5
direct variation; y= 5x
inverse variation; xy= 1/5

I think its direct variation; y=5x

Answer 1

\[5*1 = 5\]
\[5*3 = 15\]
\[5*4 = 20\]
\[5*7 = 35\]
This proves that choice C is the answer :)
