Answer:
[tex]y=x+28[/tex]
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
[tex]y-y_{1} =m(x-x_{1} )\\y-29=1(x-1)\\y=x-1+29\\y=x+28[/tex]
Where the y-intercept is at (0,28).
