Micheal Redkin and Math Basics

In order to create a graph such as the one Ms. Redkin uses to calculate the depreciation

of her rental house, first it must be determined which part of the information given is

the dependant variable and which is the independent variable. In this case the independent

variable is time (in years), and the dependent the value of the house. Next create a graph

with the given data, the independent variables on the x-axis and the dependent on the y.

Graph and label the given data as points (4 yrs, $64000) and (7 yrs, $52000), allow the

graph to represent the house's value from when it was new to 10 years after its purchase.

Graph a line from these two points, now you may follow the line to find the approximate

value of the house at certain years of depreciation. In order to find the value of the

rental house after ten years, follow the line previously graphed to 10 on the x-axis. The

y value you should receive should be 40,000, and if you were searching for the value of

the house when it was new, the graph shows $80,000 at 0 years. Another example of how this

graph may be used is in finding which year the house reaches a certain value. In order to

find out which year the house's value becomes 55,000 follow the graphed until you come

upon the value of 55,000. The x value associated with the value 55,000 is 5 years, so the

answer is the rental house will depreciate in value to 55,000 at 5 years.

The slope of the line will be required to find many other answers to questions you may

have concerning the house and its depreciation. To determine the slope of the line,
