5 is you median
4 is your mean
Equation pi X r^2 first one = 158.37
second one 50.27
When the slope is zero, the line is horizontal. Its equation will be of the form
... y = constant
The y-value of your point is specified as -9, so the equation of the line through that point is
... y = -9
What do you mean? I’m not sure
