Question

Hey I need help with this question it has 4 parts to it

Answer 1

Given:

The graph is:

Find-:

(B)

The unit rate of water usage in cubic feet per hour

(C)

Equation of line

(D)

How much water would use at the park on a Tuesday

Explanation-:

(B)

Water usage in cubic feet per hour is:

The line passes at the point (0,0) and (5,150)

Cubic feet per hour is:

`=(y_2-y_1)/(x_2-x_1)`

Where,

`\begin{gathered} (x_1,y_1)=\text{ First Point} \\ \\ (x_2,y_2)=\text{ Second Point} \end{gathered}`

In the line points are:

`\begin{gathered} (x_1,y_1)=(0,0) \\ \\ (x_2,y_2)=(5,150) \end{gathered}`

The unit rate of water is:

`\begin{gathered} =(150-0)/(5-0) \\ \\ =(150)/(5) \\ \\ =30 \end{gathered}`
