📈 The Relationship Detective
Imagine you're a detective investigating the relationship between two things - like the cost of taxi rides and the distance travelled. You notice that every extra mile costs an extra £2, and there's a £3 starting fee. This creates a perfect straight line when graphed!
Straight line graphs show constant relationships and are everywhere in real life - from phone bills to speed calculations.
