Answer:
Tara shouldn't use the fertilizer because the plant with the fertilizer had a growth rate of 3.1 millimeters per day and the plant without the fertilizer had a growth rate of 3.4 millimeters per day.
Step-by-step explanation:
This is basically a slope problem.
The equation for slope is y1-y2/x1-x2
So take two points. Time would be your X. Height would be your Y.
I chose
6 - 18.6
8 - 24.8
So: 24.8-18.6/8-6 = 3.1 The slope of the growth of the plant is 3.1 mm per day.
