It is important to know the difference between **Sketch A Graph** & **Draw A Graph**.

Sketch ==>

- On foolscap paper
- Best Representation of the graph
- Less time as it reflects only the general shape of the graph.

Draw ==>

- On graph paper
- Accurate representation of the graph
- More time needed as it usually involves more points on the graph
- Curve rule/french curve is usually required.

Example:

Sketch

What I will do :

- Find
*x*-intercept (i.e. set*y*= 0)

- Find
*y*-intercept (i.e. set*x*= 0)*y*= 1 - Put the 2 points on the axes I have drawn on foolscap, join the 2 points, label the line.

Draw

- Set up a table of 3 values of
*x*choosen randomly i.e*x*= -1 , 0, 1 - Find out values of
*y*for each value of*x*by substituting into the equation of the line. - Plot the points on a graph paper accurately.
- Join the 3 points, label the line.
