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
