Check whether the given function is in the form of y=kx or can be written in the form of y=kx.
Is x and y proportional? Yes. Constant of Proportionality: 1/2 Explanation: The equation can be written as y=kx.
Practice makes perfect
We want to determine if x and y are proportional.
x/y=2Since the given function is not in the form of y= kx, let's try to rewrite it in this form by isolating y.
We can write the equation in the form y= kx, This means that x and y are proportional. We can also identify the constant of proportionality k.
y= 12 * x
The constant of proportionality is 12.
