Step 1: Work out where the graph crosses the axes.

NOTE:  The graph will cross the x-axis when y = 0 and the y-axis when x = 0. Substitute in x = 0 and then y = 0 to determine the crossing points, and mark these on your sketch.

What happens as x becomes very large? Think about whether y will become very large, very small, positive or negative. What happens as x becomes very small (large and negative)?


Step 2: Plot this points on the xy-plane and add all the points then you will get the  required curve.

Step 3: Follow the same steps(above steps 1 and 2) for the line and locate the points at the same xy-plane.
