Calculus
10. Consider the lines [x,y,z] = [4,7,-1] + t[4,8,-4] and [x,y,z] = [1,5,4] + s[-1,2,3]. a) Show that the lines intersect at the right angle. b) find the point of intersection. please and thanks!

Calculus
thank you!

Calculus
Does the line [x,y,z] = [-2,6,5] + t[3,2,-1] lie in the plane 3x - 4y + z + 25 = 0 ? Please show work.

Calculus
Explain why a line in three-space cannot be represented by a scalar equation.

Calculus
thank you :)

Calculus
Determine an equation for the line parallel to 2x + 6y + 4z = 1 and contains the point P(3, 2, 1).

Calculus
So the final answer for this one would be [x,y,z]=[6,10,1]+1[3,4,-1]=[9,14,0] ? Thank you!

Calculus
Where does the line [x, y, z] = [6, 10, 1] + t[3, 4, -1] meet the xy-plane?

Calculus
thank you! :)

Calculus
Could you please help me with this question though, I don't understand this one: Explain why a line in three-space cannot be represented by a scalar equation. thank you!
