x1	y1	x2	y2									
0      	3    	4    	5    									
												
The general equation of the line when co-ordinates of two points are given is												
												
{{{(y-	y1)/(	y1-y2) = (x-x1)/(x1-x2)}}}										
												
{{{(y-	3    	)/(	3    	-	5    	)=(x-	0      	)/(	0    	-	4    	)}}}
												
												
{{{(y	-3      	)/(	-2      	x	-0      	) /(	-4      	)}}}				
												
{{{ 	-4      	(y+	-3      	) =	-2      	(x-	0      	)}}}				
												
-4      	y+	12      	=	-2      	x+	-0      						
												
-4      	y=	-2      	x	-12      								
/	-4      											
1      	y=	  1/ 2	x+	3
