Answer:
The second option, that is:
Time 3 6 8 10
Plant growth 2.25 4.5 6 7.5
Step-by-step explanation:
Rate is computed with points (x1, y1) and (x2, y2) as:
Rate = (y2 - y1)/(x2 - x1)
Rate of A: (6-3)/(4-2) = 1.5
Rate of the first option: (9.6 - 4.8)/(6 - 3) = 1.6
Rate of the second option: (4.5 - 2.25)/(6 - 3) = 0.75
Rate of the third option: (7.2 - 5.4)/(4 - 3) = 1.8
Rate of the fourth option: (8.4 - 6.3)/(4 - 3) = 2.1
