1. Solving for two points of a linear equation gives you the same graph for the line represented by the equation. Can you give any examples of where solving a linear equation is useful in any of our daily activities?
2. Determining the slope and y intercept is very important in graphing a solution. How would you relate slope and the y intercept in a real world case?
3. You should have noticed that when solving a linear inequality that we usually solve for y. Why do we always solve for y?
1. Solving linear equations are useful in many of our daily activities. For example, in monthly electric, water, or telephone bills, the cost to be paid is basically equal to a fixed service charge plus the cost of the usage of service. Using mobile phone bill s a concrete example, the cost formula can be dictated by a linear ...
