Answer:

See below

Step-by-step explanation:

Equation given

  • 2x + 9 + 3x + x = 6x + 9

No solution ⇒ 6x + a, a≠9

  • Parallel lines, same slope and different y-intercept

One solution ⇒ ax + b, a≠6

  • Lines with different slope

Infinitely many solutions ⇒ a(6x + 9), a≠ 0

  • Overlapping lines
