Which set of ordered pairs (x, y)(x, y) could represent a linear function? \mathbf{A}= A= \,\,\left\{(-1, -8),\,\,(1, -3),\,\,(3, 2),\,\,(5, 7)\right\} {(−1,−8),(1,−3),(3,2),(5,7)} \mathbf{B}= B= \,\,\left\{(-6, -6),\,\,(-3, -3),\,\,(0, 0),\,\,(4, 3)\right\} {(−6,−6),(−3,−3),(0,0),(4,3)} \mathbf{C}= C= \,\,\left\{(-6, 2),\,\,(-3, -1),\,\,(0, -4),\,\,(3, -6)\right\} {(−6,2),(−3,−1),(0,−4),(3,−6)} \mathbf{D}= D= \,\,\left\{(0, 4),\,\,(1, 1),\,\,(4, -5),\,\,(5, -7)\right\} {(0,4),(1,1),(4,−5),(5,−7)}
