Types of Problems[]
There is one type of problem in this exercise:
- Determine the number of solutions: This problem provides a system of two equations in two unknowns. The student is asked to determine whether the system has none, one or infinitely many solutions.
Strategies[]
Algebraic skills to manipulate algebraic forms are useful for success while doing this exercise.
- Lines that are not parallel have a single solution.
- Lines that have the same slope and y-intercept have infinitely many solutions.
- Lines that have the same slope but different y-intercepts parallel have no solutions.
Real-life applications[]
- Systems of equations are used to solve some mixture problems in chemistry.
- Systems of equations are used to solve distance, rate, time problems in physics.
- Systems of equations can be used with certain Cost and Revenue situations to find break-even points.
- Systems of equations can be used with supply and demand to find equilibrium prices.
