1.) A point (1,2,3) and the equation (x-2)^2+(y-5)^2+(z-5)^2=56, find the line (in parametric equations) from that point to the center of the sphere.

2.) Here is everything I have done

I first made a vector from 1,2,3 to 2,5,5.

<1,3,2>

and then a parametric equation

r(t)=<1,2,3>+t<2,5,5>

was this the right process

In other words, you have t multiplying the wrong vector.
