Linear function : y=mx+C , where x= independent variable, y = dependent variable and m is the slope of function.
it tells that the rate of change of y with respect to x is m.
Given : Aria bought a plant and planted it in a pot near a window in her house.
As the plant grows, its height, in inches, can be modeled by the function
[tex]H(t)=4t+16[/tex] , where t is the number of months since Aria bought the plant.
here, t= independent variable
H(t)= dependent variable
Comparing this to the general linear function , we conclude that m= 4
i.e. slope of the function = 4
Interpretation : The rate of change of height of the plant = 4 inches per month.
