Answer:
see below
Step-by-step explanation:
Comparing rates is the same as comparing slopes.
Relationship A-
Slope m = change in y/ change in x
m= (6-3)/4-2) = 3/2
Relationship B- we need a slope that is smaller than 3/2 or 1.5
For each table compute the slope by picking any two points and computing change in plant growth over change in time.
The chart with Time ( 3, 6 ,8, 10) and growth (2.25, 4.5, 6, 7.5) has a lesser slope.
Pick any point- I'll use (8,6) and (6, 4.5)
Slope = (6-4.5)/(8-6) = 1.5/2 = .75
