The graph of a linear equation in two variables is a straight line. This can be used to describe many relationships and processes in the physical world. It gives a visual representation of the relationship between two variables such as how quickly a projectile is moving or how fast a chemical reaction is proceeding. It can also be used to show the comparison between two units of measurement like centimeters and inches, meters and miles or degrees Celsius and degrees Fahrenheit. Learn how to graph a linear equation in two variables by helping Mei Long build a temple on top of a high hill in a village called Nanjie in order to house an enormous mythical dragon believed to bring prosperity and good fortune.
