A[Equation of a straight line]
A --> B[Slope-intercept form: y = mx + b]
A --> C[Point-slope form: y - y1 = m(x - x1)]
A --> D[Two-point form: (y - y1) = ((y2 - y1) / (x2 - x1)) * (x - x1)]
A --> E[Intercept form: x/a + y/b = 1]
A --> F[Normal form: x cos θ + y sin θ = p]
B --> G[m = slope, b = y-intercept]
C --> H[m = slope, (x1, y1) = point on the line]
D --> I[(x1, y1) and (x2, y2) = two points on the line]
E --> J[a = x-intercept, b = y-intercept]
F --> K[θ = angle made by the normal with positive x-axis, p = length of the normal from the origin]
