Formula and explanation
Formula: (y - y₁)/(y₂ - y₁) = (x - x₁)/(x₂ - x₁) (where x₁ eq x₂ and y₁ eq y₂ ) Conditions: Known two distinct points (x₁, y₁) and (x₂, y₂) on the line. Explanation: When two points on the line are known, the equation can be written directly without first calculating the slope.
