Here are selected entries from the 2010 tax table that show the federal income tax owed by those married and filing jointly. The taxable income and the tax are both in dollars.

Taxable income Tax
67,500 9291
67,600 9306
67,700 9321
67,800 9336
67,900 9351
68,000 9369
68,100 9394
68,200 9419
68,300 9444
68,400 9469
68,500 9494
68,600 9519

Over what two parts of this table is the tax T a linear function of the taxable income t?

67,500 ≤ t ≤ 68,200 and 68,300 ≤ t ≤ 68,600
67,500 ≤ t ≤ 68,100 and 68,200 ≤ t ≤ 68,600
    
67,500 ≤ t ≤ 68,000 and 68,100 ≤ t ≤ 68,600
67,500 ≤ t ≤ 67,900 and 68,000 ≤ t ≤ 68,600
67,500 ≤ t ≤ 67,700 and 67,800 ≤ t ≤ 68,600


Find formulas for both linear functions. (Let T be tax and t taxable income.)
