Will medal and fan! need help asap Which inequality matches the graph?

OpenStudy (f_jayyy):

Can I see the graph?

OpenStudy (anonymous):

OpenStudy (anonymous):

−2x + 3y > 7 2x − 3y < 7 −3x + 2y ≥ 7 3x − 2y ≤ 7

OpenStudy (anonymous):

@F_Jayyy

OpenStudy (f_jayyy):

Pretty sure it is B

OpenStudy (anonymous):

can you explain please? just need to understand

OpenStudy (f_jayyy):

The line cuts through those two points

OpenStudy (anonymous):

i have some more if you could help

Which correctly describes how the graph of the inequality 5x + 2y ≥ 13 is shaded? Above the solid line Below the solid line Above the dashed line Below the dashed line

OpenStudy (mathmale):

I'd suggest you graph 5x + 2y "greater than or equal to " 13. Then, choose a test point, such as the origin (0,0), substitute its x- and y-coordinates into the inequality and determine whether or not the inequality is true. Know what to do next?

OpenStudy (anonymous):

is it either a or c? because of the sign it would be above the lign but idk what the shaded and dashed lines mean

OpenStudy (curry):

get all the inequalities into a y < ... form.

OpenStudy (curry):

and post the 4 possible choices that way. Then, we can do the next step.

OpenStudy (curry):

ANd for shaded, it means the inequality is just > or <. If it's a solid line, then it can be >= or <=

OpenStudy (curry):

Implying that the graph can actually have solutions on the line, since it's greater/less than or equal to.

OpenStudy (anonymous):

so would it c?

OpenStudy (tkhunny):

Intercept form might be easier. Just taking a visual on the intercepts... \(\dfrac{x}{3½} + \dfrac{y}{-2½} > 1\) \(\dfrac{2x}{7} - \dfrac{2y}{5} > 1\) \(10x - 14y > 35\) \(2x - 2.4y > 7\) Which one looks like that? I'm not seeing it.

idk this is all the answer choices it giving me Which correctly describes how the graph of the inequality 5x + 2y ≥ 13 is shaded? Above the solid line Below the solid line Above the dashed line Below the dashed line
