The Distance between two points 

and

The Slope of a line passing through 

and 


is 

where 


Parallel lines have the same slope. 

Nonvertical perpendicular lines have slopes whose 
product is 1 
This may be written as 


Horizontal lines have a slope of 0. 
Vertical lines have no slope. (The slope is not
defined for a vertical line.) 
Slope Intercept 





Point Slope 



is a point on the line.
