Rules for Calculating the Slope of a Line
IMPORTANT NOTE:
- Find two points on the line.
- Count the rise (How many units do you count up or down to get from one point to the next?) Record this number as your numerator.
- Count the run (How many units do you count left or right to get to the point?) Record this number as your denominator.
- Simplify your fraction if possible.
IMPORTANT NOTE:
- If you count up or right your number is positive.
- If you count down or left your number is negative.
