--------
A line in 3-space has a slope wrt each of the 3 planes.
If it's treated as a vector and translated to pass thru the Origin, the direction cosines are used.
=================
3-space is a LOT more than 1.5 times as complicated as 2-space.

Find the slope of the line which goes through points (1.2, 8) and (3.6, 10).
Find the slope:
m = %2810-8%29%2F%283.6-1.2%29 = 2%2F2.4 = 1%2F1.2%29
Using point/slope form: y -y1 = m(x-x1)
y - 8 = 1%2F1.2(x - 1.2)
y - 8 = 1%2F1.2x - 1
y = 1%2F1.2x - 1 + 8
y = 1%2F1.2x + 7
Make sure you simplify the fraction into integers (if necessary) to match the definition of the Standard Form of an equation.
multiply equation by 12
12y = 10x + 84
-10x + 12y = 84
simplify, divide by -2
5x - 6y = -42; the standard form
