Im kinda lost too. And I got (0,-3,8)

I thought that was the position vectorÉ And if its parallel does that mean that CD dot product by (7,49,25) will be zeroÉ

I`m sorry I am really lost now. I subtracted (3,2,3) and (8,10,6) and got (5,8,3). So that is my position vector I hope. So as it stands the equation is r= (5,8,3) + s (xyz) + t (xyz) How do I get the other coordinates for vector s and t

Thank you for the welcome :) So I'm assuming B is (3,2,3) and C is (8,10,6) etc. In that case how would I go about finding direction vectors if they're perpendicular? Is it a combination of cross product of B and C? EDIT: Also the term coplanar, does that mean the vectors in the equation have...

Homework Statement Two coplanar lines, a and b are perpendicular to each other. a passes through the points (3,2,3) and (8,10,6). Find the equation for b if it passes through the point (7,49,25).Homework Equations The equation were trying to find is r = [x,y,z] + s [x1,y1,z1] + t [x2,y2,z2] The...
