Question 731936
x1	y1	x2	y2										
7      	-6    	6    	-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-	-6    	)/(	-6    	-	-5    	)=(x-	7      	)/(	7    	-	6    	)}}}	
													
													1      
{{{(y-	6      	)/(	-1      	)=(x	-7  ) /(	1      	)}}}					
													
{{{ 	1      	(y-	6      	) =	-1      	(x-	7      	)}}}					
													
y-	6      	=	-      	x  	-7      							
													
y=	-      	x	-1
