? 
, which is equal to -1, so 
is perpendicular to 
and is therefore the shortest route.
B. The product of the slopes of the two lines is 
? 
, which is equal to -1, so 
is not perpendicular to 
and is therefore not the shortest route.
C. The product of the slopes of the two lines is 
? 6, which is equal to 1, so 
is not perpendicular to 
and is therefore not the shortest route.
