↪Actually welcome to the concpet of the Rate of change of any Quantity with respect to time. ..
↪since for general we know that ..
↪Rate of change = ( Final state - initial state )÷( final time - initial time )
↪thus ♢d = (A2 - A1) ÷ (t2 - t1)
↪applying the formula above we get as ..
↪Rate of change of water level in feet per hour =
↪======> (Water level final - Water level initial ) ÷ ( final time - initial time )
↪since here we can take any interval of time ... we choose the second and third ..
↪thus Rate = (30 - 40 ) ÷ ( 4 -2 )
↪==》 Rate = -10 ÷ 2 ==》 -5 feet/ hr
↪since the rate cannot be negative value , we take the modulus of it
↪this Rate = |-5| = 5
↪thus Rate = 5 feet / hour

12 simply because it’s right at the middle between 6 and 18 which are the the first and third multiples of the number six
Your calculations are perfect!
Answer:
The slope is -1.8
Step-by-step explanation:
Given
The attached graph
Required
The slope
Let each box represents 1 unit on both axis.
So, we have:
![(x_1,y_1) = (-3,4)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%28-3%2C4%29)
![(x_2,y_2) = (2,-5)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29%20%3D%20%282%2C-5%29)
The slope m is calculated as:
![m=\frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![m=\frac{-5 - 4}{2 - (-3)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-5%20-%204%7D%7B2%20-%20%28-3%29%7D)
![m=\frac{-5 - 4}{2 +3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-5%20-%204%7D%7B2%20%2B3%7D)
![m=\frac{-9}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-9%7D%7B5%7D)
![m=-1.8](https://tex.z-dn.net/?f=m%3D-1.8)
