Systems of Linear Equation in Two Variables

• Systems of Linear Equation are two or more linear equations considered together to form a system
• Linear equations follows what form?

  standard form: ax+by=c
• Solution are ordered pairs that satisfies both equation
• what are the 3 classification of graphs?

  Intersecting

  Coinciding

  Parallel
• Intersecting lines have unequal slope, have one solution and considered as consistent and independent
• Coinciding lines have equal slope, equal y intercept, have infinitely many solutions and considered as consistent and dependent
• Parallel lines have equal slope, unequal y intercept, have no solution and considered as inconsistent
