## Homework Statement

Let A and B be the two points with position vectors A and B. Show that the line passing through thezse points may be represented by the vector equation:

R = sA + tB

## Homework Equations

R = Ro + tV

where Ro is a point on the line and t is some scalar, and V is a vector pointing in the direction of the line.

## The Attempt at a Solution

I have tried writing R = A + t(A - B)

and R = B + s(A - B), and manipulating the equations, however, i don't find the solution they are looking for. Could someone please help me get started on this? thank you
