Question

Which of the following ordered pairs is not a solution to the inequality y < -x + 6?
(-3, 0)
(-1, 0)
(4, 3)
(3, -2)
anyone know how to solve?

Answer 1

(4, 3)

Answer 2

you can try the points to see which one is not true
example lets try (-3,0) on equation y <-x+6
so we have

0 < -(-3) + 6
0<9 true, so this point is good

Answer 3

y < -x + 6
check it at (4, 3) where x=4 and y= 3
so 3 < -4 + 6
i.e. 3 < 2 which is false so (4, 3) is not a solution to the inequality y < -x + 6
