For this case we have that by definition, the equation in the form of slope-intersection is given by:

y = mx + b

Where

m is the slope b is the cut point

Substituting the given point: (x, y) = (2, -4) and the cutoff point b = -2 we can find the slope,

We have:

$-4 = m * 2-2\\-4 = 2m-2\\-4 + 2 = 2m\\-2 = 2m$

$m =-\frac{2}{2}\\m = -1$

Thus, the equation is given by:

y = -x-2

Hi!

Assuming the 9in is the radius, we would multiply it by 2, or add it to itself. We then get 18 in.

Hope this helps!
