Question

fill in the blanks below

1. the formula ( c = 20 + 15f ) represents the amount of ( c ) (in dollars) it will cost you for a one - time printing service of ( f ) flyers. answer the following questions

the independent variable is
the dependent variable is

1. using the previous question (6), answer the questions below

graph the function above on the graph below. on paper,
interpret the slope of the graph
interpret the y - intercept of the graph

Explanation:

Step1: Identify the linear function form

The general form of a linear function is \(y = mx + b\), where \(m\) is the slope and \(b\) is the \(y -\)intercept. In the function \(c = 15x+20\), \(x\) represents the number of flyers (independent variable) and \(c\) represents the total cost (dependent variable).

Step2: Interpret the slope

The slope \(m = 15\). In the context of the problem, for each additional flyer (\(x\) increases by \(1\)), the total cost \(c\) increases by \(15\). So the slope means the cost per flyer is \(\$15\).

Step3: Interpret the \(y -\)intercept

The \(y -\)intercept \(b = 20\). When \(x = 0\) (i.e., no flyers are ordered), the cost \(c=20\). So the \(y -\)intercept represents a fixed additional fee of \(\$20\).

Answer:

The slope of the graph means the cost per flyer is \(\$15\). The \(y -\)intercept of the graph represents a fixed additional fee of \(\$20\).
