Equation of a linear (straight line) graph
The equation of a linear graph helps you understand how two variables are related, often appearing as straight lines on a graph. This is commonly used in real-life situations like calculating the cost of a taxi ride (where the total cost depends on a base fare plus a rate per mile) or tracking distance over time at a constant speed.
