Perpendicular to 3y=x-4 and passes through the point (-2,1)

Answer 1

The product of slopes of perpendicular lines is -1. The slope of the given line is

m₁ = 1/3

The slope of the perpendicular line is

m₂ = -1/m₁ = -1/(1/3) = -3

In point slope form, the equation of the perpendicular line is

y - 1 = -3(x + 2)
