Find both the vector equation and the parametric equations of the line through (1,5,1) that is perpendicular to the lines x=3-5t, y=3+9t, z=4-5t and x=-5t, y=3+t, z=4-t, where t=0 corresponds to the given point.
The vector equation is r = (1,5,1) + t(5,-9,5)
Find the parametric equations of the line through (1,5,1) in the direction of the vector 'MXn=^
The parametric equations are x = 1 + 5t, y = 5 - 9t, z = 1 + 5t (Use the answer from the previous step to find this answer.)
