Each number is increased by ten... umm idk any other answer you want
The depth of a river changes after a heavy rainstorm. Its depth, in feet, is modeled as a function of time, in hours
y is the depth in feet and x is the time in hours
From the table we can see that
In 9 hours, the depth is 18 feet
In 18 hours , the depth is 21 feet
(9,18 ) and (18,21)
Average rate of change = 
= 
= 
= 
the average rate of change for the depth of the river is
feet per hour
<span>94.25 centimeters is your answer. Hope this helps!</span>

Answer: -2/3</h3>
==========================================
Work Shown:
Use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (-3 - 5)/(5 - (-7))
m = (-3 - 5)/(5 + 7)
m = (-8)/(12)
m = -2/3
