Question

What is the equation of this line? A. y = 2x B. y = -2x C. y = -1/2x D. y = 1/2x

Answer 1

Answer:

The equation of the line whose length of the perpendicular from the origin is p and the angle made by the perpendicular with the positive x-axis is given by α is given by: x cos α+y sin α = p This is known as the normal form of the line.
