Systems of Linear Equations
Systems of Linear Equations A system of linear equations is simply two or more lines graphed on the same graph. They are also called simultaneous linear equations, meaning that the graphs of the two lines are present at the same time.
Systems of Linear Equations When two lines are graphed on the same rectangular coordinate system, three scenarios are possible: The lines can intersect. The lines can be parallel. The lines can be coincident (same line)
Intersecting Lines If a system has one, or more solutions, it is said to be consistent. If the lines intersect: the system of equations is consistent. the equations are independent. there is exactly one solution – an ordered pair the solution will be the point of intersection (x, y)
Coincident Lines If a system has one, or more solutions, it is said to be consistent. If the lines are the same - coincident: the system of equations is consistent. the equations are dependent. there are infinite solutions – all the points on the lines the solution will be expressed in set notation. {(x, y)|x + y = 6}
Parallel Lines If a system has no solutions it is said to be inconsistent. If the lines are parallel: the system of equations is inconsistent. there is no solution set. if the solution is expressed in set notation, it is the empty
