X - y = -2
A) No
B) Yes

Question

Quizplus · Accepted Answer

To determine if the point (-4, 6) is in the solution set, substitute x = -4 and y = 6 into each equation. For the first equation, x + y = 10 becomes -4 + 6 = 2, which does not equal 10. For the second equation, x - y = -2 becomes -4 - 6 = -10, which does not equal -2. Since the point does not satisfy both equations, it is not in the solution set.
