Find the constant of proportionality for the table and write in the form y = kx.
Responses
A y = 1/10
xy = 1 10 x
B y = 90xy = 90x
C y = 10xy = 10x
D y = 9x
The constant of proportionality can be found by dividing any y-value by its corresponding x-value. Let's choose the first row as an example:
y/x = 1/10
This means that y is equal to 1/10 times x. So the constant of proportionality is 1/10.
Therefore, the answer is A: y = 1/10x.
