we know that
A relationship between two variables, x, and y, represent a directly or proportional variation if it can be expressed in the form
or 
In this problem we have
For x=-3, y=12
Find the value of the constant of proportionality k

substitute the given values

so
The linear equation is equal to

what is the value of y when x=6?
substitute the value of x in the linear equation and solve for y
