Question

How do you write a direct variation equation that passes through the point (5,-6)?

Answer 1

A direct variation equation is of the form
`y = m*x` for some constant value `m`

For a direct variation equation passing through `(x,y) = (5,-6)`
we have
`-6 = m*(5)`
`rarr m = -6/5`
and the direct variation equation is
`y = (- 6/5)x`

which you might re-write as
`5y = -6x`
