Question 469760
x1		y1	x2	y2				
-3		-1	-5	7				
								
slope m =		(y2-y1)/(x2-x1)						
(7-(-1)	)/(-5-(-3)) 
(8/-2) 				
m=-4.00						 
								
Plug value of  the slope  and point (-3,-1) in	
Y 	=	m	x 	+	b			
-1.00	=	12	+	b				
b=	-1		12					
b=	-13							
So the equation  will be								
Y 	=	-4	x 		-13

4x+y=-13
