Answer:

Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph,
change in x (time) =
minutes
change in y ( amount of the element) =
g
So, average rate of change = 
Answer:
1.8 × 40 + 32 = 104
if i got it wrong than your teacher is on crack
<u><em>Answer:</em></u>
<u><em>x
= -3 + Y/2</em></u>
<u><em>y= 6 + 2x</em></u>
