To determine which among the given points lie on the graph of the given line, substitute the values of x for the function and solve for y. The value of y in the point and the value calculated should be equal.A. (-3, 21) and = (-3)2 - 2(-3) + 6 = 21 EQUALB. (-2, 0) and = (-2)2 - 2(-2) + 6 = 14 NOT EQUALC. (-1, 10) and = (-1)2 -2(-1) + 6 = 9 NOT EQUALThus, the answer is letter A.
