Answer:
120 represents the initial Length
-8 represents the change in L when n change.
Explanation:
The equation of a straight line has the form:
y = m*x + b
Where x and y are the variables, m is the slope and b is the intercept.
So, in the equation L(n) = 120 - 8n,
L and n are the variables, -8 is the slope (number beside the variable) and 120 is the intercept.
So, we can say that 120 represents the initial value of the variable L or the initial Lenght and -8 represents how L change when we change the variable n.
