Question 425320
Find the slope of this line 								
								
y=-2.5x+4
Compare this equation with y=mx+b								
slope m =	-2.50							
								
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 	 2/5=0.40
								
m=0.40,point(1,5)	
Find b by plugging the values of m & the point in			
y=mx+b								
5=0.4+b				
b=4.6							
m= 2/5							
The required equation is y=0.4x+4.6
