Question 561091
x1		y1	x2	y2			
4      		3    	12    	8    			
							
slope m =		(y2-y1)/(x2-x1)					
(	8    	-	3    	)/(	12    	-	4    
(	5	/	8    	)  			
m=		  5/ 8					
							
Plug value of  the slope  and point (	4,	3    	) in
Y 	=	m	x 	+	b		
3.00	=	2 1/2	+	b			
b=	3	-	2 1/2				
b=	  1/ 2						
So the equation  will be							
Y 	=	 5/8	x 	+	 1/2
