Question

Which of the following ordered pairs is not a solution to the inequality y < -x + 4?

(1, 2)

(2, 1)

(4, 0)

(3, -2)

My answer is (3, -2)
Am I right?

Answer 1

let's find out!

y < -x + 4
-2 < -3 + 4
-2 < 1
that appears to be true, not false...

Answer 2

Oh ok, how about (4, 0)

Answer 3

0 < -4 + 4
0 < 0
is that true?

Answer 4

I dont believe so

Answer 5

that's correct, zero is not less than zero. So that would be the proper answer to choose if you wanted to find the statement which was not a solution.

Answer 6

Thank you! :)

Answer 7

you're welcome!

Answer 8

y<-x+4
or y+x <4
0+4<4 which is false.
(4,0) is the required solution.
