Answer :

Given: line passes through (-1, 3, -2) and is perpendicular to each of the lines and


To find: equation of line in Vector and Cartesian form


Formula Used: Equation of a line is


Vector form:


Cartesian form:


where is a point on the line and is a vector parallel to the line.


If 2 lines of direction ratios a1:a2:a3 and b1:b2:b3 are perpendicular, then a1b1+a2b2+a3b3 = 0


Explanation:


Here,


Let the direction ratios of the line be b1:b2:b3


Direction ratios of the other two lines are 1 : 2 : 3 and -3 : 2 : 5


Since the other two line are perpendicular to the given line, we have


b1 + 2b2 + 3b3 = 0


-3b1 + 2b2 + 5b3 = 0


Solving,






Therefore,


Vector form of the line is:



Cartesian form of the line is:
