Question

The enrollment at East Valley High School over a six-year period is displayed in the scatterplot.

Answer 1

Answer:

Option D is correct.

$y = \frac{81}{2}x-\frac{160,069}{2}$

Step-by-step explanation:

The equation of line of best-fit for this scatter plot is given by:

$y=mx+b$

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:

$y = 40.57x-80182$

or we can write this as:

$y = \frac{81}{2}x-\frac{160,069}{2}$

Therefore, the  equation of the line of best-fit for this scatter plot is:

$y = \frac{81}{2}x-\frac{160,069}{2}$
