(a) identify the linear term and give a possible interpretation of its meaning.

(b) identify the constant term and give a possible interpretation of its meaning.

(not multiple choice)

P(x)=5x+10

A linear term is identified as a term with a degree of 1 or just x. The linear term of the above equation is 5x.

5x means that for every change in the value of x, its factor of change is by 5 per unit.

A constant term is a term that does not change. The constant term of the above equation is 10. This means that every value that 5x produces must be added by 10 to get the total cost in dollars.
