Explanation / Answer

r = (x0,y0) + t(a,b)

Now r = (10-3t)i + (6+t)j + 2tk = (10-3t, 6+t, 2t)

=> r = (10,6,0) + t(-3,1,2)

Therefore, (x0,y0,z0) = (10,6,0) and (a,b,c) = (-3,1,2)

Now (a) r = (7,7,0) +t(-3,1,1)

(b) r = (-2,10,8) +t(6,-3,-4)

(c) r = (-5,11,10) +t(15,-5,-10) = (-5,11,10)-5t(-3,1,2)

(d) r = (4,8,2) +t(-9,5,6)

(e) r = (1,9,6) +t(-12,4,10) = (1,9,6)+2t(-6,2,5)

In all the given choices, the direction vector in part(c) = (a,b,c) = (15,-5,-10) is scalar multiple of given direction vector of given equation of line

Hence the line in option c is similar to the original line segment
