Answer: [tex]k=-\frac{2}{3}[/tex]

Step-by-step explanation:

By definition, a direct varition is expressed as following:

[tex]y=kx[/tex]

 Then, y is directly proportional to x and k is the constant of variation.

Therefore, given the direct variation:

[tex]4x=-6y[/tex]

You must solve for the variable y as you can see below:

[tex]4x=-6y\\\\y=-\frac{4}{6}x\\\\y=-\frac{2}{3}x[/tex]

Therefore, as you can see,  the constant of variation is the following:

[tex]k=-\frac{2}{3}[/tex]
