1 y = 5 x + 9
Divide by 1
y = 5 x + 9
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 -0.2
m1*m2=-1
The slope of the required line will be - 1/5

m= - 1/5 ,point ( 0 , 6 )
Find b by plugging the values of m & the point in
y=mx+b
6 = 0.00 + b
b= 6
m= - 1/5
The required equation is y = - 1/ 5 x + 6
