Find an equation of the line perpendicular to y=2x-1 and that passes through (4,1). Give the answer and slope intercept form

Answer 1

a perpendicular line has a negative inverse slope = -1/2

y = -x/2 + b

1 = -4/2 + b

b = 1+2 = 3

y =-x/2 + 3 is the equation of the perpendicular line through (4,1)
