Slope Calculation Formula
The formula to calculate the slope between two points — let’s call them (x1, y1)
and (x2, y2)
— is as simple as (y2 - y1) / (x2 - x1)
. Just a quick subtraction and division, and you’ve got your slope!
Categories of Slope Calculations
Category | Range | Interpretation |
---|---|---|
Positive Slope | > 0 | The line rises from left to right |
Negative Slope | < 0 | The line falls from left to right |
Zero Slope | = 0 | The line is horizontal |
Undefined Slope | N/A | The line is vertical |
Examples of Slope Calculations
Person | Points | Calculation | Result |
---|---|---|---|
Bob | (1, 2) and (3, 4) | (4 – 2) / (3 – 1) = 1 | Bob has achieved a slope of 1. Way to go, Bob! |
Alice | (2, 3) and (5, 6) | (6 – 3) / (5 – 2) = 1 | Alice matches Bob with a slope of 1. It’s a tie! |
