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:
[tex]=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where,
[tex]\begin{gathered} (x_1,y_1)=\text{ First Point} \\ \\ (x_2,y_2)=\text{ Second Point} \end{gathered}[/tex]
In the line points are:
[tex]\begin{gathered} (x_1,y_1)=(0,0) \\ \\ (x_2,y_2)=(5,150) \end{gathered}[/tex]
The unit rate of water is:
[tex]\begin{gathered} =\frac{150-0}{5-0} \\ \\ =\frac{150}{5} \\ \\ =30 \end{gathered}[/tex]
