-10/1 is the correct answer
<span>We know that the surface of a sphere is: S = 4 * pi * r^2
The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51
And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32
So the surface of Jupiter is around 11^2 times bigger than the Earth</span>
Do you have the problem for the linear equations
Divide change in the output value by the change in the input value for example in this question the rate on the y=+5 and on the x value it’s +1
