Math Learning Center Boise State ©2010 Linear Graphing Business Graphing is an important skill in mathematics. It gives us the ability to visualize the numerical concepts we are discussing and to develop pictures which makes the concepts easier to comprehend. The primary format of graphing used in algebra is called the Cartesian graphing system. It consists of two axes, which divides the graph into four regions called quadrants: Often we will need to graph objects which only have values that are positive or zero. In this case we only need to graph the first quadrant. The purpose for pointing this out is to build the understanding that whether we use all four quadrants or just one (or maybe two) quadrant(s), all of the techniques are the same. When graphing, one valuable tool is the t -chart. The t -chart is a simple method to list points directly below the variable in a t format. For example, if you are going to use straight line depreciation (linear depreciation) for a new wheat combine just purchased for a farm, you would have a point with time = 0 Vertical axis (y-axis) Horizontal axis (x-axis) II I III IV I Vertical axis (y-axis) Horizontal axis (x-axis)

Math Learning Center Boise State ©2010 and value = $350,000. Given a life span of about 8 years and an estimated salvage value of $30,000, your second point would be time = 8 and value = $30,000. Thus a t -chart would look like With the t -chart, we can graph the two points and connect them with a line since we are using straight line depreciation giving the following graph:
