(1 point) let f⃗ =xi⃗ +(x+y)j⃗ +(x−y+z)k⃗ . let the line l be x=3t−5, y=−(1+2t), z=−(3+2t). (a) find a point p=(x0,y0,z0) where f⃗ is parallel to l. p= (x+(3t-5),x+y+(-1-2t),x-y+z-(3+2t)) find a point q=(x1,y1,z1) at which f⃗ and l are perpendicular. q= give an equation for the set of all points at which f⃗ and l are perpendicular. equation:
