Question 545868
3x-7y=-4 and passes through the point (-6,1)

3      	x		-7	y  	=	-4				
Find the slope of this line 										
										
-7	y  	=	-3      	x		-4				
Divide by 	-7									
	y  	=	  3/ 7	x	+	0.57				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	 3/7									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										-2.33
m1*m2=-1										
The slope of the required line will be 	-7/3							
										
m=	-7/3	,point	(-6,1)			
Find b by plugging the values of m & the point in										
y=mx+b										
1	=	14.00	+	b						
b=	-13									
m=	-7/3									
The required equation is y =-7/3 x-13
