Question 454151
4y=2x+28				
Divide by 4									
y= 1/2	x		7				
Compare this equation with y=mx+b										
slope m =	0.50																		
The slope of a line perpendicular to the above line will be the negative reciprocal -2
m1*m2=-1										
The slope of the required line will be 	-2.00	
m=	-2.00	,point	(-2,11)			
Find b by plugging the values of m & the point in										
y=mx+b										
11=4.00	+b						
b=7									
m=-2									
The required equation is	y=-2x+7
