Which equation represents a proportional relationship that has a constant of proportionality equal to -10
stira [4]

Answer:

y =  - 10x

Step-by-step explanation:

A proportional relationship has equation:

y = kx

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

Therefore the correct choice is

y =  - 10x
