Sometimes called 'Rise over Run'. Or the Change of Y over the change of X
===The formula for the slope of the straight line going through the points (x1, y1) and (x 2, y 2) is given by:  ===




 =__Finding slope__:=

= = =** __Negative slope__ is a line that goes down from left to right **= =** __Positive slope__ is a line that goes up from left to right. **= = = =** __Undefined slope__ is a vertical line that has no solution. **= = = =** __No slope__ is a horizontal line that has a “x” value of zero.**=

[[image:Example_1_for_rate_of_change.png]]
A line has a slope of -2 and passes through the point (2, 5). Find another point A through which the line passes. (many possible answers)
