Question

Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7?
StartFraction y over x EndFraction = StartFraction 7 over 10 EndFraction
StartFraction y over x EndFraction = StartFraction 1 over 7 EndFraction
x y = StartFraction 7 over 10 EndFraction
x y = StartFraction 1 over 7 EndFraction

Answer 1

Answer:

  $\dfrac{y}{x}=\dfrac{7}{10}$

Step-by-step explanation:

The usual representation of a proportional relationship is ...

  y = kx

You want the constant of proportionality (k) to be 7/10, so this is ...

  y = (7/10)x

Dividing by x gives the equivalent relationship ...

  y/x = 7/10

Answer 2
