Answer:

  • y = -2x +6
  • y = -x
  • 2y = 6x -4

Step-by-step explanation:

a)

Any line with a different slope (x-coefficient) will give a system with one solution. For example,

  y = -2x +6

__

b)

Any line with the same x-coefficient and a different constant will give a system with no solutions. (The lines will be parallel.) For example,

  y = -x

__

c)

Any multiple of the same equation will give a system with an infinite number of solutions. For example, we can multiply the equation by 2 to get ...

  2y = 6x -4
