Question

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.

Answer 1

The unit rate is 3 $/ft

Explanation:

Answer 2

The unit rate is 3 $/ft

Explanation:

Let

x ----> the number of feet

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

we have

y=3x

Remember that

A connection between two factors, x, and y, speak to a relative variety on the off chance that it tends to be communicated in the structure y/x=k or y=kx

In a corresponding relationship the steady of proportionality k is equivalent to the incline m of the line and the line goes through the source

In this problem we have a proportional relationship

The unit rate is a similar that the slant of the straight capacity or the steady of proportionality k

so

m=k=3 $/ft

therefore

The unit rate is 3 $/ft
