Question

Which equation has a constant of proportionality equal to 0.2
A. 10y=10x
B. Y=15x
C. 3y=30x
D. 10y=2x

Answer 1

Answer:

equation (D.) has a constant of proportionality equal to 0.2

explanation:

  10y=2x

   y=(2/10)x

   y=0.2x

   

so  y $\alpha$ x   with constant of proportionality = 0.2
