Vector Line Equations

$R^2$

From Origin

?

Notation

?

• Set of all possible lines that pass the point
• If through origin, no (0 3)
• All pos

$R^3$

Finding the line through 2 points

• Have one initial point, then it is parallel to the vector joining the two points
  • The difference between the 2 points, the slope

Ex) Line through 2 points (0,0,2) and (1,4,6) ?

• Pick a point, then add the difference of the two points

Vector definition of plane in $R^3$ ?

• 2 parameters t and s, therefore a 2 dimensional object
• If u is a scalar multiple of v, then it is ;; a line not a plane

ex) v = 2u

What is the plane of u=(1,3,2) and v=(-1,4,2) ?

• t(1,3,2) + s(-1,4,2)
