Let 
be the equation of the perpendicular line.
Two perpendicular lines have slopes with product equal to -1. The slope of the given line is 
Hence,
is the slope of needed line.
This line passes through the point (-4,2), so its coordinates satisfy the equation:
Therefore, the equation of the line is

Answer:
There is about 4,164/4,165 chances of not getting getting a four of a kind. So, it is extremely unlikely or even borderline impossible in that situation to get a four of a kind.
