Answer:
![y = - 10x](https://tex.z-dn.net/?f=y%20%3D%20%20-%2010x)
Step-by-step explanation:
A proportional relationship has equation:
![y = kx](https://tex.z-dn.net/?f=y%20%3D%20kx)
where k is the constant of proportionality.
Since we are looking for a proportional relationship that has a constant of proportionality equal to -10, we have k=-10.
We substitute k=-10 into the equation to get:
![y = - 10x](https://tex.z-dn.net/?f=y%20%3D%20%20-%2010x)
Therefore the correct choice is
![y = - 10x](https://tex.z-dn.net/?f=y%20%3D%20%20-%2010x)
