Calculation Types

Two Points: Calculate slope using two points on a line
Point-Slope Form: Find equation using a point and slope
Slope-Intercept Form: Work with y = mx + b form

Slope Formula

For two points (x₁, y₁) and (x₂, y₂):

m = (y₂ - y₁) / (x₂ - x₁)

Line Equations

Point-Slope Form: y - y₁ = m(x - x₁)
Slope-Intercept Form: y = mx + b
Standard Form: Ax + By = C

Examples

Points (2,4) and (6,8): slope = 1
Point (3,7) with slope 2: y = 2x + 1
Slope 3, y-intercept 5: y = 3x + 5
