You can put this solution on YOUR website! A)($3.30, 10.5) ($2.50, 8.5) m = 2/.8 = 2.5
 y[s] - 8.5 = 2.5(x -2.5)
 y[s] = 2.5x + 8.5 -6.25
 .......
 ($2.50, 10.5)
 (3.50, 7.8) m = 2.7/-1 = -2.7
 y[d] -10.5 = -2.7(x - 2.5)
 y[d] = -2.7x + 10.5 + 6.75
 B) y[s] = y[d]
 2.5x + 2.25 = -2.7x + 17.25
 x = 15/5.2 = 2.8846 million bushels
