# What Is The Difference Between Sketch And Draw?

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 $y=-3x+1$

What I will do :

1. Find x-intercept (i.e. set y = 0)
$x=\frac{1}{3}$
2. Find y-intercept (i.e. set x = 0) y = 1
3. Put the 2 points on the axes I have drawn on foolscap, join the 2 points, label the line.

Draw $y=-3x+1$

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