Darby graphed the equation y = 4x + 6 on a graph. Samuel graphed the line defined by the table. 5
02
y 6 14
-3
-6
26
Which of the statements correctly compares the two functions?
A
Both functions have the same y-intercept but different slopes; therefore, Darby and Samuel have graphed the same line.
B.
Both functions have the same slope but different y-intercepts; therefore, Darby and Samuel have graphed parallel lines.
с
Both functions have the same y-intercept and the same slope; therefore, Darby and Samuel have graphed the same line.
D
Both functions have the same slope and the same y-intercepts; therefore, Darby and Samuel have graphed parallel lines.

The variance of the given sample is 7.3

Hence the option A. 7.3 is correct

Step-by-step explanation:

The formula of Variance is:

x                                  

10                                           4

15                                           9

8                                           16

16                                          16

14                                           4

12                                           0

9                                             9

12                                            0

14                                            4

10                                            4

                                          

Therefore, the variance is:
