Answer:
<h2>a = - 4.8</h2>
Step-by-step explanation:
To find the value of a when b=6 we must first find the relationship between them.
The statement
a is inversely proportional to b is written as

where k is the constant of proportionality
When a = 7.2 , b = -4
So we have

k = 7.2 × - 4
k = - 28.8
So the formula for the variation is

When
b = 6
That's

We have the final answer as
<h3>a = - 4.8</h3>
