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

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
