Original function:

  • y = 2x

Added 2 to the original function:

  • y = 2x + 2, this shifted the graph 2 units up

Subtracted 4 from  the original function:

  • y = 2x - 4, this shifted the graph 4 units down
  • y=2x+2
  • y=2x-4

Original

  • y=2x

Shift 2 units upwards

  • y=2x+2

Shift the graph 4 units down

  • y=2x-4
