Question

Which equation represents a proportional relationship that has a constant of proportionality equal to StartFraction 4 over 5 EndFraction?
y = x + StartFraction 4 over 5 EndFraction
y = StartFraction 4 over 5 EndFraction x
x y = StartFraction 4 over 5 EndFraction
x + y = StartFraction 4 over 5 EndFraction
