Question 550994: The water level of a river is 34 feet and it is receding at a rate of 0.5 foot per day. Write an equation that represents the water level, w, after d days. Identify the slope and y-intercept and describe their meanings. In how many days will the water level be 26 feet? Answer by TutorDelphia(193) (Show Source):
The slope is -.5 which is our rate of change for the water level
The y intercept is 34 which is our water level after 0 days.
26=-.5d+34
-8=-.5d
16=d
It'll be at 26 in 16 days.
