In this, you will study about locating a point on the graph.
15.2.2 – Coordinates
In this, you will study about the Cartesian system. Here the horizontal line of the axes is called the x-axis and the vertical line is called the y-axis.
15.3 – Some Applications
In this, you will study the applications of graphs which are used to study data in various field.
