Step-by-step explanation:
Since it's a direct variation
y = kx
where k is the constant of proportionality
To find the value of y when x = –0.5 we must first find the relationship between the variables
When
x = 3
y = 2
2 = 3k
Divide both sides by 3

So the formula for the variation is
<h3>

</h3>
When x = - 0.5 or - 1/2

We have the final answer as
