Estimate the line of best fit using two points on the line.

A. y = x + 12

Step-by-step explanation:

Given the two points:

A = (x1, y1) =  (6, 8)

B = (x2, y2) = (9. 6)

From the photo, we can see that the line of fest fit is a straight line (linear) that go through the two points above.

We have the standard form of a linear equation is:

where m is the slope and b is the y-intercept

To find the slope, we use the following formula:

m =

<=> m = =

Substitute m into the standard equation, we have:

Because the line go through point A, so we substitute A into (1), we have:

8 = *6 + b

<=> b = 12

So our equation is: y = x + 12

hi friend

here is your answer

there are two angles that are alternate interior angle with angle 9

the angle 15 and angle 7 are alternate interior angle with angle 9.

hope it is for you so mark my answer as a brainliest
