<h3>What is the average of a group of numbers?</h3>
The average of the group of numbers is the ratio of the sum of all the numbers of the group to the total number of the group.
Lisa is currently taking physics as one of her electives in school.
Her grade at the end of the year is determined by the average of four exams, each worth 100 points.
- On her first test, she got an 84,
- On her second, she got a 92,
- On her third, an 80.
She got exactly 80% in the course. Let she scores x marks in her fourth exam. Thus,

Answer:
y=3/4x +3
Step-by-step explanation:
Find the slope first. y-y over x-x
Y: 9-6 =3
X 8-4 = 4
so the slope is 3/4
Now choose one of the ordered pairs to use to substitute to find the y intercept or "b" in y=mx + b
I chose 4,6 since the slope has a 4 in the denominator
Use y=mx + b
Y =6 from ordered pair m/slope= 3/4 x= 4 from ordered pair and you are looking for b
6= 3/4 (4) + b
6= 12/4 or 3 + b subtract 3 from both sides
3= b
equation is y=3/4x +3
