		GRAPHED SYSTEMS OF EQUATIONS #3--KEY

Directions: Find the solution for each system of equations below.  Express your answer in the form of an ordered pair that identifies where the two equations intersect on the graph.

Solution    (2, 4)

Solution    (4, -3)

Solution    (1, 1)

1)     x + y = -2	                                       2)    8x + 4y = 20		                    3)   y = x + 2

        y = 1                                                         x + 4y = -4                	                          y = 0.2x + 3.6 

NO SOLUTION

Solution    (-3, -1)

Solution    (-5, 6)

4)     x = -5	                                       5)    3x + 4y = -12		                     6)   y = 6x + 17

        x + y = 1                                                  6x + 8y = 32                	                           y = -3x - 10 

	

Solution    (0, -12)

Solution    (16, 8) 
168)

Solution    (16, -20) 1)

7)     y = -20	                                       8)    16y - x = 112		                    9)   8y = -2x - 96

        x = 16                                                     -3x + 3y = -24                	                y = 2x - 12
