1)    Write a system of linear functions that will have NO solution

 

 

 

 

2)    Write a system of linear functions that will have INFINITE solutions

 

 

 

 

Determine if the following systems will have none, infinite or one solution

 

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

    y = -2x + 3                                          -12x + 4y = 16

 

 

 

 

5) y = -3x + 1                                      6) 3x – 5y = 0

    y = 3x + 7                                          

 

 

 

7) Write a linear function that will be parallel to y = 3x + 4 and has an initial value at -1.

 

 

 

8) Write a linear function that will be perpendicular to y =  and whose graph will pass through (-3, 7)

 

 

 

 

9) Put the following linear functions in y = mx + b to determine if they are perpendicular
