### Why Do We Make Graphs?

Every algebraic calculation is associated with graphs, and every equation can be plotted on the coordinate grid system according to the values of its variables. A graph is plotted according to a few guidelines. Firstly, an individual who wants to plot certain values of the variables of an equation must initially define a key. Key is the length on either axes that represent the reading of a value ‘1’. For example, on a graph, we can determine a centimeter box as the reading for a value of one for both axes. After determining the key, we consider drawing axes on the graph. The horizontal axis is known as the x-axis extended at both ends representing positive and negative values. Similarly, the vertical axis is known as the y-axis extended at both ends representing positive and negative values. The point about which both these axes are extended is known as the origin and has a coordinated value of zero on both the axes. After solving an equation for the values of its variables, one plots the coordinates according to their values on both the axes and connects all the points to form a linear graph.
