Question

Does the equation represent a direct variation if so find the constant variation
5x=-3y

A. No
B. Yes k=-5/3
C. Yes k=5/3
D. Yes k= -3/5

Answer 1

Answer:

B. Yes k=-5/3

Step-by-step explanation:

$5x = - 3y \\ - 3y = 5x \\ y = \frac{5}{ - 3} = x \\ y = - \frac{5}{3} x \\ equating \: it \: with \: y = kx..(k = constant) \\ k = - \frac{5}{3}$

Hence, the equation represent a direct variation with constant of variation k = - 5/3.
