Study Notes
Solving Systems of Equations
-
Elimination Method: Involves adding or subtracting two equations to remove one variable, simplifying the problem to solve for the remaining variable.
-
Substitution Method: Involves expressing one variable in terms of the other variable and substituting this back into the original equation to solve for the variables.
-
Graphing Method: A visual approach that involves plotting the equations on a coordinate plane and identifying the point of intersection which represents the solution.
Types of Solutions
-
Unique Solution: Occurs when two lines intersect at a single point; this results in one solution for the system. The lines must have different slopes.
-
Infinitely Many Solutions: Happens when two lines are completely overlapping; this indicates that the lines have identical slopes and y-intercepts, leading to an infinite number of solutions.
-
No Solution: Characterized by two parallel lines that never intersect; these lines have the same slope but different y-intercepts, indicating that there is no point at which the equations are satisfied simultaneously.
