Answer:
![y=x+28](https://tex.z-dn.net/?f=y%3Dx%2B28)
Step-by-step explanation:
All coordinates are
(1,29); (2,30); (3,31); (4,32); (5,33); (6,34); (7,35); (8,36); (9,37); (10,38); (11,39); (12,40).
So, what we need to do is to find the line that best fit this data.
Now, notice that x-values and y-values both increase 1 unit, that means the constant ratio of change is 1, which is also defined as the slope of the line that bets fits.
Then, we need to use the point-slope formula and one point
![y-y_{1} =m(x-x_{1} )\\y-29=1(x-1)\\y=x-1+29\\y=x+28](https://tex.z-dn.net/?f=y-y_%7B1%7D%20%3Dm%28x-x_%7B1%7D%20%29%5C%5Cy-29%3D1%28x-1%29%5C%5Cy%3Dx-1%2B29%5C%5Cy%3Dx%2B28)
Where the y-intercept is at (0,28).
