Rate of change prob? each of the following is the slope of a line representing daily revenue y in terms of time x in days. use the slope to interpret any change in daily revenue for a one day increase in time.
a) m=400 b) m=100 c) m=0

Slope = Rise / Run
Slope = "change in y" / "change in x "
   
Since x = Days and y = Daily Revenue
(how much money they make each day)
 then Slope = "change in daily revenue" / " number of day"

if m =400 then for each day, a net daily revenue of 400 dollars is gained
if m =100 then for each day, a net daily revenue of 100 dollars is gained
if m= 0     then for each day,  no net daily revenue  is gained
