Answer:
The average rate of change is 4
Step-by-step explanation:
To find the values of y when x = 0 and when x = 2, we can graph the equation using a graphing calculator.
Looking at the graph, we can see that when x = 0 y = 5 and when x = 2 y = 13
Now that we have two points (0,5) and (2,13) we can find the rate of change
To find the rate of change we use this equation:
Let's input the values from our two points
Simplify: = 4
We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with ,
,
, and
respectively since each one is 1 point more than the last.
Add all of these values up and set it all equal to .
Now, simplify.
Subtract on both sides.
Divide both sides by .
Since Louise's score is , the answer is
.
To verify our answer, add the point totals ,
,
, and
.
This equals , so we can be sure the answer is correct.
