Answer:

Option A

Explanation:

Given is the scatter plot for x and y and the possible regression line closer to all the points.

We have to find the equation of the line

We can find two points on the line from the graph and find the equation using two point formula

We find y intercept is 6 i.e. one point (0,6)

Let us take any other point say for

x=10 , y = 21

Hence two points are (0,6) and (10,21)

Using two point formula we get

$(x-0)/(10-0) =(y-6)/(21-6) \\15x=10(y-6)\\1.5x=y-6\\y=1,5x+6$

Hence option A is right
