Question

FAN AND MEDAL OF COURSE PLEASE I JUST NEED HELP
Which of the following points lie in the solution set to the following system of inequalities? y < -3x + 3 y < x + 2 (1, -5) (1, 5) (5, 1) (-1, 5)

Answer 1

(1,-5)...x = 1 and y = -5
y < -3x + 3
sub in your points
-5 < -3(1) + 3
-5 < -3 + 3
-5 < 0 (true)

y < x + 2
-5 < 1 + 2
-5 < 3 (true)

Thats basically how you do it. You sub in your set of points in BOTH inequalities, and if it comes out true in both of them, it is a solution. I didn't check the other ones, so I do not know if there is more then 1 answer. But (1,-5) is a solution
