Find a parametrization for the line segment joining the points P(0,3,0) and Q(0,3,3). Draw coordinate axes and sketch the segment, indicating the direction of increasing t for the parametrization. Find the parametrization for the line segment joining the two points. Use (0,3,0) as the base point and PQ as the vector. Let y = 3 x = .y=].z=].osts (Type expressions using t as the variable.)
