Question

many students wrote the equation, L(n)=120-8n. what does the 120 represent? what does the -8 mean?l=length n=number of the variable

Answer 1

120 represents the initial Length

-8 represents the change in L when n change.

Step-by-step 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.
