Question

Do these equations represent direct variation. If so please identify their constant of variation.

2x-1/5y=0

3y=5-4x

Answer 1

Yes they both are direct relationships

Answer 2

Yes, these both are direct relationships and can be written like
`y = kx`, where k is the constant of variation.

For the first equation, k = 10. For the second equation, k = -4/3. You find it by rearranging the equation into the form
`y=kx`, and you use the coefficient of x for k.
