Answer:
k=2/3
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x = k or y = kx
In this problem we have 3y = 2x
Isolate the variable y
Divide by 3 both sides
y = 2/3x
Remember that
In a proportional relationship the constant of proportionality k is equal to the slope m of the line
The slope of the line m is
m = 2/3
therefore
The constant of proportionality k is
k = 2/3
I hope this helped have a wonderful day/night ! <3 (depends what time it is)
