Slope Relationship of Two Parallel Lines
Relationship: If lines L₁ and L₂ are parallel, then their slopes are equal, i.e., k₁ = k₂. Conditions: Both lines are not perpendicular to the x - axis (i.e.,…

Formula and explanation
Relationship: If lines L₁ and L₂ are parallel, then their slopes are equal, i.e., k₁ = k₂. Conditions: Both lines are not perpendicular to the x - axis (i.e., their slopes exist). Explanation: This is a common condition for determining if two lines are parallel. For lines perpendicular to the x - axis (slope undefined), they are parallel if and only if their x - coordinate constants are equal.
