------------------
You have two points; generate an equation to find income:
Points: (3,25000.00) and (23,68000..00)
slope = (68000-25000)/(23-3) = (43,000/20) = 2150
intercept: 25000= 2150*3 + b
b = 18550
-----
Equation:
income = 2150(months) + 18550
income(23) = 2150*23 + 18550
income(23) = 68,000
