Question

If the ordered pairs in this problem are for the same direct variation, how do you find the Missing value (2,3) and (6,y)?

Answer 1

A direct variation equation has the form
`y = cx` for some constant `c`

If `(x,y)=(2,3)` is a point on the required direct variation
then
`3 = c*2`
`rarr c= 3/2`

For the point `(6,y)` on this same direct variation we have
`y = (3/2)x`

`= 3/2*6`

`=9`
