Pls, help. I am very not smart :')

x 4 7 10 13 7 6.4 11.2 16 20.8 Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.

To determine whether y varies directly with x, we need to check if the ratio of y to x is constant.

Let's find the ratios of y to x for each pair of corresponding values:

y/x = 4/y, 7/4, 10/7, 13/10, 7/13, 6.4/7, 11.2/6.4, 16/11.2, 20.8/16

As we can see, the ratios are not all the same, so y does not vary directly with x.

Therefore, we cannot find the constant of variation k or write the equation for this situation.

To determine whether y varies directly with x, we need to check if there is a constant ratio between the values of y and x.

Let's examine the given values of x and y:

x: 4 7 10 13 7 6.4 11.2 16 20.8
y:

We can see that we only have the values for x and not y. Could you please provide the values of y corresponding to each value of x?
