The ordered pair (-3,0) is a solution of which system ? needed ! 10 points.

So what I would do is plug in the point into each system:

#1:

y > 0        (-3,0) since y = 0, plug in 0 for y

0 > 0       This can't be true because they are = to each other, so you would need to have a sign of either ≤ or ≥ (less/greater than or equal to) for the point to be a solution to the system

#2 is the same "0 < 0" can't be true

#3

0 ≤ 0 this is true

y > x + 9     Plug in the point (-3,0)

0 > -3 + 9   Simplify

0 > 6 This is false because 0 is not greater than 6

#4

0 ≥ 0    This is true

0 < -3 + 9

0 < 6     This is true because 0 is less than 6

>       4th option is your answer

is there answer choices?
