Equation of a line in the plane which is perpendicular to the line whose equation is and which passes through the point of intersection of is
Let direction ratios of the line be (a, b, c ,) then 2a-b+c=0
Therefore, direction ratios of the line are (3, 5, - 1).
Any point on the given line is it lies on the given plane if
or
Therefore, the point of intersection of the line and the plane is (1, 3, 5).
Therefore, equation of the required line is
