Question 427292
5x-y=7	
Find the slope of this line 						
-y=-5x-7	
Divide by -1						
	y =5x+	7	
Compare this equation with y=mx+b							
slope m =5.00						
							
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 -0.20			-0.2	=
							
m=-0.20	,point	(2,9)
Find b by plugging the values of m & the point in							
y=mx+b							
9=-0.4+b			
b=9.4						
m=-0.2						
The required equation is	y=-0.2x+	9.4
