**Line Drawing Algorithm**

Y
= mx+b (1)

is represent as a line equation where m is the slow and b the y intersects at the line.

tan θ = y/x

m = 〖y_2-y〗_1/(x_2-x_1 ) (2)

so,

m = 〖y_2-y〗_1/(x_2-x_1 )

from the equation 1 and 2

b = y1-x1m (3)

if the interval correspondent to y axis is called

del y and del x then

del y = m del x (4)

m = (del y)/(del x) (5)

There are two type of the line algorithm: -
