Question

How do you find the constant of proportionality in the equation y = kx?

Answer 1

To find the constant of proportionality (k) in the equation y = kx, you need to have specific values for both y and x.

Once you have a set of coordinates (x, y) from a given situation or data, you can substitute these values into the equation.

For example, let's say you have the coordinates (2, 5). You can substitute these values into the equation:

5 = k * 2

Now, you can solve for k by dividing both sides of the equation by 2:

5/2 = k

So, the constant of proportionality (k) in this case is 5/2.
