Answer:
Option D is correct.
[tex]y = \frac{81}{2}x-\frac{160,069}{2}[/tex]
Step-by-step explanation:
The equation of line of best-fit for this scatter plot is given by:
[tex]y=mx+b[/tex]
where, m is the slope and b is the y-intercept.
As per the statement:
The enrollment at East Valley High School over a six-year period is displayed in the scatter-plot.
Student Enrollment at East Valley High School
Here, x represents the number of years and y represents the number of students.
Enter the values of x into one list and the values for y into the second list.
You can see the graph of the scatter plot as shown below in the attachment.
we get, the equation of line is:
[tex]y = 40.57x-80182[/tex]
or we can write this as:
[tex]y = \frac{81}{2}x-\frac{160,069}{2}[/tex]
Therefore, the equation of the line of best-fit for this scatter plot is:
[tex]y = \frac{81}{2}x-\frac{160,069}{2}[/tex]
