Question 582694
4      	x	+	7	y  	=	2				
Find the slope of this line										
										
7y=-4x	+2    				
Divide by	7									
	y  	=	-  4/ 7	x	+	 2/7				
Compare this equation with y=mx+b,	m= slope & b= y intercept					
slope m =	- 4/7									
										
The slope of a line perpendicular to the above line will be the negative reciprocal  7/4
m1*m2=-1										
The slope of the required line will be			1 3/4							
										
m=	7/4	,point	(	2	,	3	)			
Find b by plugging the values of m & the point in										
y=mx+b										
3	=	7/ 2	+	b						
b=	- 1/2									
m=	7/4									
The required equation is	y =	(7/ 4)x-  1/ 2
