Calculus grade 12

1. a) Write the vector and parametric equations of the line through the points A(6, 1, 5) and B(2, 3, 6).
b) Find another point on the line in (a).

r = 6ij+5k + t(8i2j+k)
x = 68t
y = 12t
z = 5+t 
Can you please do b) Steve? Thank you.

Steve, for a) I got this instead:
vector equation:
[x, y, z] = [6, 1, 5] + t[8, 2, 1]
parametric equation:
x=6+t(2)
x=62t
y=1+t(3)
y=13t
z=5+6t
is that correct? ...
