1) (1,+ and-6,-1) is not a point but if anything it is two points (1, 6,-1) andOriginally Posted bykingkaisai2

(1,-6,-1).

2) By the distance from the point p to the line r(t) I take it that you mean

the minimum distance.

One way (not necessarily the simplest) to do this is to write:

,

then differentiate this with respect to t and set the derivative to zero and

and solve the resulting equation for t, which will give the t corresponding to

the closest point on the line to the given point, which can then be used to

find the actual minimum distance.
