Find a vector equation for the line through the point P = (4, -1, 2) and parallel to the vector v=(1,1,-4).
Note: there are many correct answers to this question, so in order for webwork check your answer, you need to find the particular vector equation that has r(0)=P and v as the direction vector of the line. Use the variable t as the parameter. This amounts to solving the problem in the standard way.
r(t) = i + j + k
Rewrite this in terms of the parametric equations for the line.
x =
y =
z =
