Given the data set (5, 9), (13, 12), (23, 16), which of the following equations best represents a line of best fit? a) y = 3/4x − 7 b) y = 4/5x + 7 c) y = 2/5x + 7 d) y = 2/3x − 7

Option C -                                        

Step-by-step explanation:

Given : Data set (5, 9), (13, 12), (23, 16).

To find : Which of the following equations best represents a line of best fit?

Solution :

Data (5, 9), (13, 12), (23, 16).

We plot the data points on the graph and get the best fit line.

Using regression calculator,

The function has a linear behavior so the best line which represent the data is given by

Approx

or

and the value of R² i.e. correlation coefficient is given by

which is approximately equal to 1 gives you the best fit line.

From the given options,

gives you the best fit line.

Therefore, Option C is correct.
