Answer:

[tex]x=0[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

in this problem

For x=32, y=-4

Find the value of the constant of proportionality k

[tex]k=y/x[/tex]

substitute

[tex]k=-\frac{4}{32}[/tex]

simplify

[tex]k=-\frac{1}{8}[/tex]

so

The linear equation is

[tex]y=-\frac{1}{8}x[/tex]

Find x when the value of y=0

Remember that

In a proportional relationship the line passes through the origin

so

If y=0

then

the value of x must be equal to zero

therefore

[tex]x=0[/tex]
