Question 454895
x+2y=5		
Find the slope of this line 								
make y the subject							2
y=-x+5		
Divide by 2							
y=-0.5x+	2.5		
Compare this equation with y=mx+b								
slope m =-0.5							
The slope of a line parallel to the above line will be the same								
The slope of the required line will be 			-0.5					
m=-0.5	,point	(2,9)	
Find b by plugging the values of m & the point in								
y=mx+b								
9=-1.00	+b				
b=10							
m=-0.5							
Plug value of  the slope  and b	in y = mx +b			
The required equation is	y=-0.5x+	10
