Consistent and Dependent System
Consistent and Dependent System
A system of equations where the lines coincide, meaning they have infinitely many solutions because they share all points.
Consistent and Independent System
Consistent and Independent System
A system of equations where the lines intersect at a single point, having one unique solution.
Inconsistent System
Inconsistent System
A system of equations where the lines are parallel, meaning they have no solutions because they never intersect.
