Ex 11.2, 4 Find the equation of the line which passes through the point (1, 2, 3) and is parallel to the vector 3๐ ฬ + 2๐ ฬ โ 2๐ ฬ . Equation of a line passing through a point with position vector ๐ โ, and parallel to a vector ๐ โ is ๐ โ = ๐ โ + ๐๐ โ Since line passes through (1, 2, 3) ๐ โ = 1๐ ฬ + 2๐ ฬ + 3๐ ฬ Since line is parallel to 3๐ ฬ + 2๐ ฬ โ 2๐ ฬ ๐ โ = 3๐ ฬ + 2๐ ฬ โ 2๐ ฬ Equation of line ๐ โ = ๐ โ + ๐๐ โ ๐ โ = (๐ ฬ + 2๐ ฬ + 3๐ ฬ) + ๐ (3๐ ฬ + 2๐ ฬ โ 2๐ ฬ)
