Pipe cost $3 per foot. the equation y = 3x relates the cost of a piece of pipe (y) to the number of feet (x). identify the unit rate
in the equation.

The unit rate is

Step-by-step explanation:

Let

x ----> the number of feet

y ----> represent the cost of a piece of pipe

we have

Remember that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a proportional relationship

The unit rate is the same that the slope of the linear function or the constant of proportionality k

so

therefore

The unit rate is
