Answer:

  • All four are linear
  • Slopes: 2, 1/2, - 2/3, 3/4

Step-by-step explanation:

Top left

Rate of change is same for each step:

  • 10 per each 5

Slope is:

  • (25 - 15)/(5 - 0) = 10/5 = 2

Top right

Rate of change is same for each step:

  • 1 per each 2

Slope is:

  • (6 - 5)/(3 - 1) = 1/2

Bottom left

Rate of change is same for each step:

  • -2 per each 3

Slope is:

  • (30 - 32)/(5 - 2) = -2/3

Bottom right

Rate of change is same for each step:

  • 3 per each 4

Slope is:

  • (20 - 17)/(5 - 1) = 3/4
