Hello I need help on re writing my answer or answer it more clearly

my answer is the one underlined below

Consider the following data on fertility (births per 1000 women aged 15-44) and the personal

exemption tax savings (the real value of the annual reduction in income taxes for each child you

have in 1967$) for the years 1913-1927 taken from L.A. Whittington, J. Alm, and H.E. Peters

(1990), "Fertility and the Personal Exemption: Implicit Pronatalist Policy in the United States,"

American Economic Review 80, 545-556.

The question:

Interpret, in plain language, the slope and intercept coefficient estimates you have derived. Note that the coefficient estimated on the first 15 observations is very different from what the authors obtain with the full sample and additional control variables.

B0 (intercept) refers to Y when x=0 that means the x does not affect to y , so y equals b0 if no other element to affect them

B1 this means that if the tax exemption increases by one unit, fertility will decrease by 0.43
