Question 546382
x1		y1	x2	y2				
-4		7	8	16				
								
slope m =		(y2-y1)/(x2-x1)						
(	16	-	7	)/(	8	-	-4	) 
(	9	/	12	)  				
m=		  3/ 4						 
								
Plug value of  the slope  and point 			(	-4	,	7	) in	
Y 	=	m	x 	+	b			
7.00	=	-3    	+	b				
b=	7	-	3    					
b=	4      							
So the equation  will be								
Y 	=	 3/4	x 	+	4
