A line is defined by the equations x = 3-4t, y = 8t, and z = 6+t
a) Determine the vector and symmetric equations of the line
b) Determine the values of a and c if the point (a, 2, c) lies on the line.
I have part a) solved: (x,y,z) = (3,0,6) +t(-4,8,1)
(3-x)/4 = y/8 = z-6/1
I am a little unclear has to how I would solve for a and c though in part b)
y-2/8 = a-x/4 = z-c/1 but I am not sure where to go from there...
