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=1t ; (2,0) (2,4)
b) x=5+t y=3t ; ((6,3) (3,6)
