Which equation represents a proportional relationship that has a constant of proportionality equal to –10?
a) y=x-10

b) y= x
-
-10

c) y= -10x

d) y= -10 -

p. s \\ b is x over -10

Option C

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 or

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

In this problem we have

the equation of the line is equal to

substitute the value of k
