Introduction to Graphs

This topic discusses various tools to represent data like bar graph, pie graph, histogram and line graph with the help of diagrams for each. We will also learn to interpret them here.

This topic defines a linear graph as a diagram that shows a link or relationship between two quantities or more. Therefore, the linear graph is nothing but a straight line or straight graph that is drawn on a plane connecting to the x and y coordinates points.

The topic explains that the relation between a dependent and independent variable can be shown through a graph. It covers some problems dealing with quantity and cost, simple interest, and time and distance.
