Answer to Question #6077 in Algebra for kenzie

Question

Which ordered pair is NOT a solution of the inequality y < 3 – 2x?


(-1, 3)

(6, -7)

(0, 4)

(-4, 5)

Answer 1

first pair
3 < 3 - 2(-1)
3<5 is a solution.

Second pair
-7 < 3 - 2*6
-7 < -9 is NOT a solution

Third pair
4 < 3 - 2*0
4 < 3 is NOT a solution

Forth pair
5 < 3 - 2*(-4)
5 < 11 is a solution

So solution are the next pairs: (6, -7) (0, 4)
