Algebraic Formulas

• Slope Formula: m = (y₂ - y₁) / (x₂ - x₁).
• Slope-Intercept Form: y = mx + b, with m as slope and b as y-intercept.

• Intercept Form (Quadratic Functions): y = a(x - p)(x - q), where p and q are x-intercepts.
• Vertex Form (Quadratic Functions): y = a(x - h)² + k.

Sequences and Interest Formulas

• Arithmetic Sequence Definition: Each term increases by a constant value called the common difference.
• Arithmetic Sequence Formula: a₁ + (n - 1)d.
• Geometric Sequence Definition: Defined recursively as Aₙ = A(n-1) * r, where r is the common ratio.
• Simple Interest Formula: I = Prt, where I is interest, P is principal, r is rate, and t is time.
• Compound Interest Formula: A = P(1 + r/n)^(n*t), where n is the number of compounding periods.

Coordinate Geometry

• Distance Formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²], used to calculate distance between two points.
