If y varies directly with x, we have a relation that is:
[tex]y=kx[/tex]where k is a constant.
If we know a point, we can find the constant as:
[tex]k=\frac{y}{x}=\frac{-4}{32}=-0.125[/tex]Now we have to calculate x for y=-0.375:
[tex]\begin{gathered} y=kx \\ x=\frac{y}{k}=\frac{-0.375}{-0.125}=3 \end{gathered}[/tex]The value for x is 3.
