📊 Practical Examples of Slope Calculator
✅ Example 1: Basic Coordinate Calculation
Let’s say you have two points:
- (2, 3)
- (6, 11)
When you input these values:
- Slope = (11 − 3) / (6 − 2)
- Slope = 8 / 4 = 2
So, the slope is 2, meaning the line is rising steeply upward.
✅ Example 2: Negative Slope Scenario
Consider these points:
- (4, 10)
- (8, 2)
Calculation:
- Slope = (2 − 10) / (8 − 4)
- Slope = -8 / 4 = -2
So, the slope is -2, meaning the line is going downward from left to right.
