Answer:
The correct options are A and B.
For option A:
Sy = y = 3x - 10
Substituting x = -8 and y = 4:
4 = 3(-8) - 10
4 = -24 - 10
4 = -34
Since the left-hand side does not equal the right-hand side, (-8,4) is not a solution to the system.
For option B:
y = -1x + 10
Substituting x = -8 and y = 4:
4 = -1(-8) + 10
4 = 8 + 10
4 = 18 - Incorrect
For option C:
y = 5x + 24
y = 5(-8) + 24
y = -40 + 24
y = -16 - Incorrect
For option D:
y = 6x + 68
Substituting x = -8 and y = 4:
4 = 6(-8) + 68
4 = -48 + 68
4 = 20 - Incorrect
For option E:
y = -3x + 7
9 = -3(-8) + 7
9 = 24 + 7
9 = 31 - Incorrect
Therefore, options A and B are incorrect.
