An integer is any whole number (not fractions) that can be either negative or positive.
1 is the only integer because 0.5 and 3/2 are not whole numbers and are fractions, while 1 is a whole number.
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 = 
5 points not 10 but
5/8 each day
5 days=5 times 5/8=5/1 times 5/8=25/8=24/8+1/8=3+1/8=3 and 1/8
3 and 1/8 mile
<h2>Solution :- </h2>
Let the number be "x" , then according to the question :
• 2x - 12 = -8
Further solving
→ 2x = -8 + 12
→ 2x = 4 .
→ x = 2
