SUMMARY
The problem requires finding the equation of a line through point P(-1,1,2) that is parallel to the line defined by points Q(-3,0,4) and R(3,2,1). To achieve this, first calculate the direction vector of the line through Q and R by subtracting the coordinates of Q from R, resulting in the vector (6,2,-3). This vector serves as the direction for the line through P. The final equation can be expressed in parametric form using point P and the derived direction vector.
