1 September 01, 2016 Bell Ringer: Given the following slopes and intercepts, write the linear equation. A) m = 3/2 b = 9 B) m = -7 b=0 C) m = -1 b=3 D) m = 0 b = -6 Thinking with Mathematical Models Investigation 2.3: Tree Top Fun Focus: What strategies do you use in writing equations for linear functions?
2 Tree Top Fun: Equations for Linear Functions Tree Top Fun (TTF, for short) runs adventure sites with zip lines, swings, rope ladders, bridges, and trapezes. The company uses mathematical models to relate the number of customers, prices, costs, income, and profit as its many locations. Textbook page 38 When finding an equation, it may help to calculate the values of the dependent variable for some specific values of the independent variable. Then you can look for a PATTERN in those calculations. You can use the information given in words, tables of data, and graphs.
3 Remember to try using the slope-intercept formula when writing equations. Part A Use what you know about linear equations to work out the models for the TTF business. Find an equation for each of the linear functions described below. 1. The standard charge per customer at TTF is $25. Write an equation that relates the daily income I to the number n of customers. 2. Each TTF site has operating costs $500 per day. Write an equation that relates daily profit P to the number n of customers.
4 Part A Cont. 3. One TTF site bought a new rope bridge for $4,500. TTF will pay monthly payments of $350 until the bill is paid. Write an equation for the unpaid balance B after m monthly payments. Part B 1. Explain how you know the relationship between the admission fee for a group and the number of people in the group is linear. 2. What are the slope and y-intercept of the graph of the data? 3. What equation relates rental charge A to number n in the group?
5 Part C The owners of Tree Top Adventures opened a snack bar at one site. The graph below shows the income from snack sales for six different days. What is the equation of the linear model on the graph? Part D Suppose you are asked to write an equation of the form y = mx + b to represent a linear function. What is your strategy for each situation? 1. You are given a description of the function in words. Find slope, m, by deciding what the ind. and dep. variables are. Look for a rate of increase or decrease. Y-intercept, b, by looking for a starting value. If a starting value isn't given, use the rate of change to work backward to the value of y is when x is zero.
6 Part D Suppose you are asked to write an equation of the form y = mx + b to represent a linear function. What is your strategy for each situation? 2. You are given two or more (x, y) values or a table of (x, y) values. Determine the rate of change, m, by using Then, substitute given values of x and y into the equation y = mx + b and solve to find b. Slope = y 2 - y 1 x 2 - x 1 September 01, 2016 Part D Suppose you are asked to write an equation of the form y = mx + b to represent a linear function. What is your strategy for each situation? 2. You are given two or more (x, y) values or a table of (x, y) values. Write an equation for a line that passes through the points (0,15) and (5,3).
7 Part D Suppose you are asked to write an equation of the form y = mx + b to represent a linear function. What is your strategy for each situation? September 01, You are given a graph showing points with coordinates. Find the coordinates of 2 points the line passes through. Determine the slope using slope = RISE Look on graph to find (0, b) or substitute given values of x and y to find b. or RUN Slope = y 2 - y 1 x 2 - x 1 Part E A state mathematics test asked students to find equations for linear function. Two students, Dana and Chris, gave answers below. 1. To find an equation for the line with slope -3 that passes through the point (4, 3), Dana wrote the following steps. Is she correct? Explain.
8 Part E 2. Too find an equation for the line that passes through the points (4, 5) and (6, 9), Chris wrote the following steps. Is he correct? Explain. QUIZ TIME
