Match each recursive formula with the equation of the line that contains the sequence of points, (n, un), generated by the formula.
a. u0 = - 8 ...................................... A. y = 3x - 11
un = u(n -1) + 3 where n ≥ 1 .................. B. y = 3x - 8
b. u1 = 3 ........................................ C. y = 11 - 8x
un = u(n -1) - 8 where n ≥ 2 .................. D. y = - 8x + 3
