Question 501727
4	x	+	3	y  	=	6	
Find the slope of this line 							
							
3	y  	=	-4	x	+	6	
Divide by 	3						
	y  	=	-1.333	x	+	2	
Compare this equation with y=mx+b							
slope m =	-1.33						
							
The slope of a line perpendicular to the above line will be the negative reciprocal							
m1*m2=-1							
The slope of the required line will be 			0.75				
							
m=	 3/4	,point	(	4	,	2	)
Find b by plugging the values of m & the point in							
y=mx+b							
2	=	3.00	+	b			
b=	-1						
m=	 3/4						
The required equation is y  	=	  3/ 4	x-1
