  • Algebra Skillz 6

    Solve  the  System  by  Graphing:    

    !    𝑦 = 2𝑥 + 3          𝑦 =  –3𝑥 − 2  

         

    !    2𝑥 + 7𝑦 = 14          5𝑥  +  7𝑦 =  –7  

         Solve  the  System  with  Substitution:    

    !    𝑦 = −6𝑥 + 7          3𝑥 + 𝑦 =  −2    

         

    !    3𝑥  +  𝑦   =  −19    𝑥 − 𝑦 = −7                    

         Solve  the  System  with  Elimination:    

    !    4𝑥 + 𝑦 = 17        7𝑦 =  4𝑥 − 9  

           

    !  8𝑥 + 3𝑦   =  −9        −8𝑥  +  𝑦   =  29        

       

  • Determining  the  Number  of  Solutions        𝑦 = 5𝑥 + 10          𝑦 =  5𝑥 − 2          

         

       15𝑥 − 3𝑦 = 12𝑦 = 5𝑥 − 4          

           −12𝑥 + 3𝑦 = 18        4𝑥 + 𝑦 =  −6                

         

     Graphing  Systems  of  Inequalities:        𝑦   <  2𝑥  +  2          𝑦 ≥    – 𝑥  –  1              

                     

       𝑦   <  3                      𝑥   >  −1            

         𝑦   >  3𝑥  −  3
