Answer:

k = 5,

y = 5x

Step-by-step explanation:

If y is proportional to x,

y ∝ x

Then the equation will be

y = kx

Her k = proportionality constant.

Now we choose a point from the given table.

Let the point is (2, 10).

By putting the values of x and y in the equation,

10 = 2×k

k = [tex]\frac{10}{2}[/tex]

k = 5

This will be true for any point we choose from the table.

And the equation will be y = 5x
