Special case of linear equations: Vertical lines

Lessons

1. Determine the line of equations from the following points
   
   i) $(-5,2), (-5,3)$
   ii) $(-3, 4), (-3,8)$
   iii) (b,n), (b,m)
2. Write the equation of the line with the given information.
   
   1. Vertical, passes through (3,5)
      
   2. vertical, passes through ($-{5 \over 8}, -5)$
3. A line with an undefined slope passes through the points (-2,1) and (p,q). what are the possibilities of (p,q)?
