Answer:
y-2=1/3(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=1/3(x-3)
As the diameter is 18, a radius is half the diamater ergo the radius is 9.
Use the circumference formula:

So, adapted it would be:
2 * π * 9 which would be 56.7.
The circumference is 57m.
Hope this helps!

Answer:
y = x/2 - 7
Step-by-step explanation:
First, we need to find the slope of the given equation: x - 2y = 8
Subtract x from both sides
x - 2y = 8
- x - x
-2y = 8 - x
Divide both sides by -2
-2y/-2 = (8 - x)/-2
y = -4 + x/2
The slope of this equation is 1/2
So the equation of our parallel equation is y = x/2 + b
We have to find b, so plug in the given coordinates
-6 = 2/2 + b
-6 = 1 + b
Subtract 1 from both sides
-6 = 1 + b
- 1 - 1
b = -7
Plug it back into the original equation
y = x/2 - 7
