After studying vectors we were given a sheet with questions to practice for exams. There is one question which I don't understand how they got that answer.
Question : Consider the plane with equation 4x-2y-z=1 and the line given by the parametric equations
x = 3-2t
y = (2k-1)+t
z = -1+kt
Given that the line is perpendicular to the plane, find a) the value of k ;
Any help in advance would be appreciated thanks.
The answer is K = 1/2 if you want to check if you solved it correctly.
