Question 783310
4      	x	+	-3	y  	=	2				
Find the slope of this line										                                                                                                            
										
-3	y  	=	-4      	x	+	2    				
Divide by	-3									
	y  	=	1  1/ 3	x	+	- 2/3				
Compare this equation with y=mx+b,					m= slope & b= y intercept					
slope m =	1 1/3									
										
The slope of a line perpendicular to the above line will be the negative reciprocal										- 3/4
Because m1*m2 =-1										
The slope of the required line will be			- 3/4							
										
m=	- 3/4	,point	(	1	,	2	)			
Find b by plugging the values of m & the point in										
y=mx+b										
2	=	-  3/ 4	+	b						
b=	11/4									
m=	- 3/4									
The required equation is		y  	=	-  3/ 4	x	+	11/ 4	

		
multiply by 4

4y=-3x+11

3x+4y=11
