Question 56671
  I need to write the equation of the line passing through the given pairs of points.  I need to write the result in slope-intercept form, where possible:

  (2, -3) and (2, 4)

 Notice that both the x's are 2.  If you were to plot the points and connect the dots, you'd have a vertical line going through x=2.  That is a special case.  Vertical lines can't be written in slope intercept form because their slope is undefined and they don't cross the y axis, though x=0 is the y-axis.
The equation of this line is x=2.
Happy Calculating, Ashley!!!
