Question

HELP!

Answer 1

A) Rate of change is 0.208
Rate of change is change in Y divided by the change in X. Let Y be the Dosage. Let X be the Weight.
Subtract first dosage from the second:
7.5 - 5 =2.5

Subtract the first weight from the second:
36 - 24 = 12

Now divide:
2.5 ÷ 12 = 0.208

b) It is linear. Instead of subtracting the first from the second, just subtract the second from third:
10 - 7.5 = 2.5
48 - 36 = 12

Or the third from the fourth
12.5 - 10 = 2.5
60 - 48 = 12

Or the fourth from the fifth
15 - 12-5 = 2.5
72 - 60 = 12

What do you notice? You get 2.5 and 12 for all of them, thus the relationship is linear.
