The slope tells us about the change of weight of the newborn baby with respect to the change in time in months.
The weight in pounds w of a newborn baby after t months of its birth can be modelled by the equation as,
w = 1.75t+6
The above is the equation of a line. The slope of the equation is 1.75.
Rearranging the equation,
(w-6)/t = 1.75
Here, the slope tells us that how is the weight of the new born is changing
with respect to the change of the time after its birth.
So, let us say that if the the baby's weight at some time is 7 pounds, then using the above relation, we can find out the exact month of that weight,
1/t = 1.75
t = 0.57 months.
So, the slope tell us about the linear relation between the weight in pounds and the time in months.
