Draw the graph of the equation At what point does the graph of the equation cuts the axis and axis?
Modify the equation as follows in order to get the form of equation of straight line :
For , therefore, lies on the graph. Similarly, for therefore, lies on the graph.
Now plot the points A and B and join them as shown in the figure below, to get the line AB.
Hence, from the figure, you can see that the graph (line AB) cuts the x-axis at the point and the y-axis at the point .
