Answer:
y=2x
Step-by-step explanation:
Hey!
This is a direct variation problem:
Direct variation describes a simple relationship between two variables . We say y varies directly with x.
y=kx, where k is the constant of variation or constant of proportionality.
==================================================================
We can substitute x and y in the given equation.
40=k20
Divide by 20 on both sides.
40/20=k
k=2
Substitute k in the Direct variation Equation:
y = 2x
==================================================================
Hope I helped, feel free to ask any questions to clarify :)
Have a great day!
