Can u help

Directrix (directrix):

The graphs intersect at (0,3). So, which option can be eliminated based on that. That is, which option of inequalities does not intersect at (0,3) ?

OpenStudy (sparklestaraa):

B?

OpenStudy (sparklestaraa):

@Directrix

Directrix (directrix):

(0,3) makes both inequalities of option B true. Look again.

OpenStudy (sparklestaraa):

ohhhh A because its a different sign??? @Directrix

Directrix (directrix):

Not what I had in mind. Does the point (0,3) make both of these true? y ≤ -2x + 3 y ≤ x + 3

OpenStudy (sparklestaraa):

Nooooo im guess

Directrix (directrix):

3 ≤ -2 * 0 + 3 yes or no

OpenStudy (sparklestaraa):

Yes

OpenStudy (sparklestaraa):

@Directrix is that wrong @Notamathgenius

Directrix (directrix):

3 ≤ -2 * 0 + 3 3 ≤ 0 + 3 yes
