Slide 6:
The Trend Equation - Yc = a + bx
Hence,
Y = 13 + 0.75x
Y1990 = 13+0.75 (-3) = 13-2.25 =10.75
Y1991 = 13+0.75 (-2) = 13-1.50 = 11.50
Y1992 = 13+0.75 (-1) = 13-0.75 = 12.25
Y1993 = 13+0.75 (0) = 13-0 = 13.00
Y1994 = 13+0.75 (1) = 13+0.75 = 13.75
Y1995 = 13+0.75 (2) = 13+1.5 = 14.50
Y1996 = 13+0.75 (3) = 13+2.25 = 15.25
