Interactive Coordinate Plane & Distance/Midpoint Explorer
Plots coordinate points on a Cartesian plane, calculating Euclidean distance, segment midpoint, slope, and line equations.
Input Coordinates (String Buffered):
Point A (x₁, y₁)
x₁
y₁
Quadrant II (-, +)
Point B (x₂, y₂)
x₂
y₂
Quadrant IV (+, -)
Presets:
Distance d(A, B)10√100 units
Midpoint M(1, -1)((x₁+x₂)/2, (y₁+y₂)/2)
Slope m & Angle θ-0.75θ = -36.9°
Slope-Intercept Eqy = -0.75x - 0.25y = mx + b
Step-by-Step Algebraic Forms & Derivations
Equation Forms:
• Point-Slope: (y - 2) = -0.75(x - -3)
• Standard Form (Ax + By = C): 6x + (8)y = -2
• Perpendicular Bisector: y = 1.33x - 2.33
Cartesian Coordinate Plane
The Cartesian coordinate plane specifies each point uniquely in a plane by a pair of numerical coordinates, representing signed distances from two perpendicular axes.
Formula & Step-by-Step Calculation
d = √[(x₂ - x₁)² + (y₂ - y₁)²], M = ((x₁+x₂)/2, (y₁+y₂)/2), m = (y₂ - y₁) / (x₂ - x₁)
Distance, midpoint, and slope equations.
Worked Step-by-Step Examples
Example 1
Point A(-3, 2) and Point B(5, -4)
Solution: Distance d = 10.000, Midpoint (1.00, -1.00), Slope m = -0.750, Equation: y = -0.75x - 0.25
• dx = 5 - (-3) = 8; dy = -4 - 2 = -6; d = √(64 + 36) = √100 = 10; m = -6 / 8 = -0.75

Frequently Asked Questions
Q: What is the slope of a horizontal line?
A horizontal line has a slope of 0 because dy = 0. A vertical line has an undefined slope because dx = 0.
