Question

Does y=-4/5x represent a direct variation is yes,identify the constant of variation

Answer 1

Most likely yes... there is a problem in the way you asked your question ...

if the question is
`y = ( (-4)/(5)) x` then the answer is yes and the constant is -4/5's

If by some chance the actual question is
`y = (-4)/((5x))` (you can not tell by the way y0u presented tis problem.. then the answer would be NO it would be "inverse" relation
