Answer:
exact form: 13 over 6
decimal form: 2.16
mixed number form: 2/ 1 over 6
slope is 1/3
Explanation:
We apply the slope formula:
The Mean would increase to 82.17 or a total increase of .17
You have 99 students and the avg is 82, therefore we can multiply 99*82 to get our total points
99*82=8118
We add a single score of 99 to our total points 8118+99= 8217
Then we add the student to the total number of students bringing it to 100 and divide our new total by the our new number of students.
8217/100 = 82.17
