the point (0, -2) is a solution to which system of equations?

Question

A. -x + y = 2
-x + 2y = 16

B. -4x + y = 6
-5x + y = 16

Answer 1

A. -x + y = 2

Substitute x = 0 and y = -2 into the first equation:

-(0) + (-2) = 2
-2 = 2

This is not true, so (0, -2) is not a solution to system A.

B. -4x + y = 6

Substitute x = 0 and y = -2 into the first equation:

-(4 * 0) + (-2) = 6
-2 = 6

This is not true, so (0, -2) is not a solution to system B.

Therefore, the point (0, -2) is not a solution to either system of equations.
