Which of these ordered pairs is a solution to the inequality 4x + y > –6? (Points : 1) (1, –12) (0, –9) (–1, –1) (–3, 0)

OpenStudy (anonymous):

sub the values in x and y and see

OpenStudy (anonymous):

4(1)+(-12)> -6 4-12>-6 -8>-6 this not right so this point is not a solution

OpenStudy (anonymous):

well thats thats the question

OpenStudy (anonymous):

try the other pairs

OpenStudy (anonymous):

2 point (0,-9) 4(0)+(-9)>-6 0-9>-6 this also not right so it is not a solution

OpenStudy (anonymous):

so its either c or d

OpenStudy (anonymous):

4(-1) + (-1) > -6

OpenStudy (anonymous):

is that right^

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

ok whats the next step

OpenStudy (anonymous):

you could try D also to see if it could be a point or not
