The total increase (in dollars), the average yearly increase, and the total percentage increase according to the given graph are to be determined. Concept Introduction: Graph is a way of representing numerical data in the form of a chart. A graph makes the analysis of data a little bit easier, for example, it is easy to detect the overall decrease or increase of a particular substance over a wide range. A two-dimensional graph has two axis. One is the y-axis, which is the vertical axis, whereas, the other is the x-axis, which is the horizontal axis. Certain quantities can be obtained with the help of graph analysis. These are: Total change can be determined by subtracting the highest value from the lowest. Average yearly changes can be found out by dividing the total change by a total number of years. Total percentage can be determined by dividing the total change by the first value and multiplying by 100 . Yearly percentage can be calculated by dividing the total percentage change by a total number of years.
