State a single multiple linear regression model that defines straight-line models relating Y = 5-year post surgical change in refractive error (diopters) to X1 = baseline refractive error for both males and females. Be sure to define all terms.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

hm let me think hm think think hm think yes

570, the answer is 570, hope it
