Question 485781
-6	x	+	8	y  	=	3					
Find the slope of this line 											
											
8	y  	=	6	x	+	3					
Divide by 	8										
	y  	=	 3/4	x	+	0.38					
Compare this equation with y=mx+b											
slope m =	0.75										
											
The slope of a line perpendicular to the above line will be the negative reciprocal= -4/3	
m1*m2=-1											
m=	-4/3	,point	(	-3	,	-15	)				
Find b by plugging the values of m & the point in											
y=mx+b											
-15	=	4.00	+	b							
b=	-19										
m=	-4/3										
The required equation is y=(-4/3)x-19
