For each of the following, find the parametric equations of the line that passes through the point P with direction vector d. In each case, find two points on the line different from P.

a) P(1,1) d=(4,-4)

b) P(5,0) d=(1,3)

answer at the back of the book is:

a) x=1+t y=1-t ; (2,0) (-2,4)

b) x=5+t y=3t ; ((6,3) (3,-6)
