Answer:

Option C

[tex]y=-10x[/tex]

Step-by-step explanation:

we know that

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

In a direct variation the constant of proportionality k is equal to the slope m

In this problem we have

[tex]k=m=-10[/tex]

the equation of the line is equal to

[tex]y=kx[/tex]

substitute the value of k

[tex]y=-10x[/tex]
