Question
Question:
A service charges a flat setup fee of 40 dollars plus 12 dollars per hour. Part a: Write a linear function that represents the total cost C in dollars as a function of hours h. Part b: Identify the slope and y-intercept and explain what each means in context. Part c: Create an input-output table for h equals 0, 1, 2, 3, 4, and 5 hours. Part d: Graph the function on a coordinate plane with an appropriate scale. Part e: Use the graph to estimate the total cost for 3.5 hours of service.
Real-World Linear Function: Writing & Interpreting a Graph
This lesson builds a complete linear function from a real-world pricing scenario, connecting the equation C(h) = 12h + 40 to its slope, y-intercept, input-output table, and graph. Students practice writing, interpreting, and using a linear function in slope-intercept form to make predictions.
In this lesson, you will learn to:
• Write a
