Question

Can someone help me with this?

In class, we learned to find the constant of proportionality for ratios using y=kx. Would y be the numerator and x the denominator? Or vice versa?

Answer 1

Answer:

just have a look at this

Step-by-step explanation:

y = kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
