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 3 $/ft

Step-by-step 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

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
