(x-30)+(x+76)=180
x-30+x+76=180
2x+46=180
2x=134
x=67
67-30=37
67+76=143
<1=37, <2=143

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 1993}} &,&{{ 14220}}~) 
% (c,d)
&&(~{{ 1997}} &,&{{ 9780}}~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{9780-14220}{1997-1993}\implies \cfrac{-4440}{4}\implies -1110$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-14220=-1110(x-1993)
\\\\\\
y-14220=-1110x+2212230\implies y=-1110x+2226450$
