Take 13.79 divided by 14.95 and the answer is . 92, meaning that 13.79 is 92% of 14.95. Then you need to take .92 from 1.00, resulting in .08, which is the discount.
Find slope (y2-y1)/(x2-x1) Pick points: (1,10) , (2,8) (8-10)/(2-1) = -2/1 = -2 Y = -2x + b 10 = -2 + b, b = 12 It would be the first response 12 = initial while -2 is rate of change
