B. y = 2x

Step-by-step explanation:

every y value is the value of x multiplied by 2

so that means y=2x

hope this helps luv <3

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!

what i would say the best answer is a. 40.5

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
