📈 Line Equation Forms & Properties
Slope-Intercept Form: y = mx + b (m = slope, b = y-intercept).
Point-Slope Form: y - y₁ = m(x - x₁).
Parallel Lines: Have equal slopes (m₁ = m₂).
Perpendicular Lines: Slopes are negative reciprocals (m₁ · m₂ = -1).
Frequently Asked Questions (FAQ)
What is the Slope & Line Equation Calculator and how does it work?
Analytic geometry tool. Given two points $P_1(x_1, y_1)$ and $P_2(x_2, y_2)$, calculates slope $m$, y-intercept $b$, distance $d$, and axis intercepts.
How do I use this Slope & Line Equation Calculator?
Enter coordinates for Point 1 ($x_1, y_1$). Enter coordinates for Point 2 ($x_2, y_2$). View slope $m$, y-intercept $b$, distance $d$, and inclination angle $\theta$ in degrees.
What mathematical formula is used in this calculation?
Slope: m = (y2 - y1) / (x2 - x1). Y-intercept: b = y1 - m*x1. Distance: d = √((x2-x1)² + (y2-y1)²). Angle: θ = atan(m) * (180/π).
