Assume that the price of your primary residence changes linearly over time. Fill in the information below according to the documents for your residence and your best recollection of the price of it when you purchased it. Then you will answer the questions that follow.

Year of purchase:
Purchase price:
Actual Price:

GRADES:
Remember that the data or numbers ARE NOT THE VARIABLES. Also, remember that Year is also not a variable.
Familiarize yourself with the rubric to correct this assignment. It specifies what you are expected to answer in each case, as well as how each question will be marked.

1. Identify which is the independent variable and which is the dependent variable. Write the representation that each variable will have according to function notation. DO NOT USE THE CLASSICAL NOTATIONS, x or f(x) OR THE LETTERS FOR THE EQUATIONS (x, y). (Value: 2 points)

a. Independent variable:

b. Dependent variable:

2. Predict how the relationship between the variables will be, directly or inversely proportional. What will be the sign of the slope for this case? (Value: 2 points)

3. Draw the graph that relates both variables according to the data provided. Plot the line through the points represented by the ordered pairs for the information provided. Correctly identify each axis with its units of measure. Put a title that briefly explains what is presented in the graph. (Value: 5 points)

4. Determine the slope that relates the variables according to the line drawn above. Interpret what that slope means according to the variables. (Value: 2 points)

5. Determine the linear function that expresses the relationship between the variables, according to the line drawn above. Do not confuse linear function notation with that of a linear equation. (Value: 2 points)

6. Assuming linear behavior continues over time, predict what your residence will be worth five years from the current year. YOU SHOULD MAKE THE PREDICTION assuming that the function is NOT domain restricted. (Value: 2 points)
