3.1 “Solving Linear Systems with Graphing” Systems of equations mean more than one linear equation. The point of intersection (x,y) is the solution to the system. Example: Graph the linear system and estimate the solution. 4x + y = 8 2x – 3y = 18 Steps: Solve each equation for y. Graph each line on ONE graph. Label the point of intersection (which is the solution).

Example #1 Continued 4x + y = 8 2x – 3y = 18

Try This: 8x – y = 8 3x + 2y = -16

Number of Solutions of Systems One Solution – the solution is the point where the lines intersect (x, y). Parallel – the lines never intersect, therefore, there is no solution, no points are common. Same Line - the lines are the exact same, therefore, they have infinite solutions…all points are common.

Examples: 12x – 9y = 27 8x – 6y = 18 4x + 6y = 18 6x + 9y = 18

Types of Systems: Classifications: Knowing this… Example #1? Inconsistent System – no solutions Parallel Lines Consistent System – has at least one solution Dependent – infinite number of solutions Same Line Independent – has exactly one solution Intersect Knowing this… Example #1? Example #2? Example #3? Example #4?
