Question 552103
6	x	+	8	y  	=	13				
Find the slope of this line 										
										
8	y  	=	-6	x	+	13				
Divide by 	8									
	y  	=	-0.750	x	+	1.63				
Compare this equation with y=mx+b										
slope m =	- 3/4									
										
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=	-11									
m=	4/3									
The required equation is		y  	=	4/ 3	x		-11
