Question

Solve for y when x = 15

Answer 1

y = 75

Explanation:

We know

If y = 10, then x = 2

meaning

If y = 5, then x = 1

So,

y = ?, then x = 15

We take

5 x 15 = 75

So, y = 75, when x = 15

Let's check by using the y = kx method they give!

k = 5

x = 15

y = 5(15)

y = 75

So, my answer is correct.
