🔍How It Works
Slope Formula
Slope=
y₂-y₁
x₂-x₁
Also known as "rise over run"
Slope Interpretation
Positive slope: line rises from left to right
Negative slope: line falls from left to right
Zero slope: horizontal line
Special Cases
Vertical lines: have undefined slope (division by zero)
Horizontal lines: have zero slope
🌍Real-World Applications
🏗️ Construction
Roof pitch, ramp gradients, road grades
📊 Economics
Rate of change in prices, profit margins
⛷️ Sports
Ski slope steepness, running track banking
🚗 Engineering
Highway gradients, drainage systems
💡Calculator Tips & Best Practices
⚠️Watch for Vertical Lines
If x₁ = x₂, the slope is undefined because you'd divide by zero
💡Order Doesn't Matter
You can use either point as (x₁, y₁) - just be consistent with your order
⭐Check Your Signs
Pay careful attention to positive and negative coordinates when calculating
💡Visualize the Line
Try to picture the line in your head - does your slope make sense?
❓Frequently Asked Questions
What if x₁ equals x₂?
If x₁ = x₂, you have a vertical line, and the slope is undefined (division by zero). Vertical lines have no finite slope.
What does a slope of 1 mean?
A slope of 1 means for every 1 unit you move right, you move 1 unit up. This creates a 45° angle with the horizontal.
Can slope be a fraction?
Yes! A slope of 2/3 means for every 3 units right, you move 2 units up. Fractions are very common in slope calculations.
How do I remember the slope formula?
Remember 'rise over run': slope = (rise)/(run) = (change in y)/(change in x) = (y₂-y₁)/(x₂-x₁).
