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

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