|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 ...
