Student Enrollment at East Valley High School (1st picture)

Which is the equation of the line of best-fit for this scatterplot? (2nd picture)

(it's the last one)

Answer 1

D 100% corect took my test $$$$$$$$$$$$$$

Answer 2

Option D is correct.

`y = (81)/(2)x-(160,069)/(2)`

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 = (81)/(2)x-(160,069)/(2)`

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

`y = (81)/(2)x-(160,069)/(2)`
