Answer:
a) 
b)
when 
Step-by-step explanation:
since y varies inversely with x.
We need to find the constant, k.
Let's use a point (x,y) on the curve.
We are given an (x,y)=(5,10):
Multiply both sides by 5:

.
So the equation is:

What is y when x=2?


Step-by-step explanation:
By the formula of slope, we have
