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 :

Find x-intercept (i.e. set y = 0)
$x=\frac{1}{3}$
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 $y=-3x+1$

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.
