Answer:
b - read explanation if you are confused for future problems
Step-by-step explanation:
Inverse variation is when x*y = k whereas direct variation (may come up in future problems) is when y = x*k
Remember that k is always a set value while x and y are values that can change
In this case y*x = k so k = 18 (since y is 9 when x is 2)
So when x = 8
8y = 18
y = 18/8 = 9/4
