Y=mX+b WHERE m=SLOPE & b=THE Y INTERCEPT.
USING THE POINTS (0,3927) & (4,3800)
SLOPE=(3800-3927)/(4-0)
SLOPE=-127/4
SLOPE=-31.75
3927=-31.75*0+b
3927=b
b=3927
Y=mX+b
Y(9)=-31.75*0+3927
Y=-31.75X+3927
Y=-31.45*9+3927
Y=-285.75+3927
Y=3641.25 STORES IN 2005.
Y(14)=-31.75*14+3927
Y=-444.50+3927
Y=3482.5 STORES IN 2010
