Today, students studied the graph application in practical situation, distance vs. time, related with linear graph. The slope in the linear relation is speed of the movement of distance with time. Because of the straight line of the relationship, the speed is constant. On the other hand, when the relation of distance vs time is not linear, the slope is varying, indicating that the speed of movement is changing. The change is identified as decrease and increase of speed, depending upon the slope changing trend, increasing or decreasing. The graph of distance vis time reveals the information of movement status and the speed. Also, the multiple movement graph can be used to determine the relations among the different cases, such as when/where they meet.
