1) B

For A:

3 = 4(1)

This is NOT true.

For B:

-4 = 4(-1)

This IS true.

For C:

-1 = 4(-4)

This is NOT true.

For D:

-4 = 4(1)

This is NOT true.

2) None. Possible solutions: (0,2) (1,-5)

For A:

2 = -7(1) + 2

2 = -7 + 2

This is NOT true.

For B:

-52 = -7(8) + 2

-52 = -56 + 2

This is NOT true.
