Here's the question you clicked on:

The acceleration of a falling object due to gravity varies inversely with the square of the object's distance from the center of the Earth, x =1 Earth radius, the acceleration is y = 9.8 m/s^2 - Use the multiply-multiply pattern of power function to find the acceleration at 3 and 9 radii from the center. -Find the particular equation expressing y as a function of x
wouldn't x = 1 just be the distance from the Earth's core?
so where are you having difficulties?
it sounds like a ratio and proportion question
