Answer: (a) 8 (b) 16 (c) 24 (d) The ratios are the sameStep-by-step explanation:(a) For inputs -5 and -4, the difference of outputs is ... -3 -(-11) = 8__(b) For inputs 0 and 2, the difference of outputs is ... 45 -29 = 16__(c) For inputs -3 and 0, the difference of outputs is ... 29 -5 = 24__(d) The ratios of output difference over input difference are ... 8/1 = 16/2 = 24/3 = 8 . . . . . they are all the sameThis is yet another confirmation that the slope of a line is the same everywhere, and over any interval.
