Which graph best represent the inequality? pictures down below , Thank you all &lt;3
kow [346]

Answer:

y ≤ 3x+1

Step-by-step explanation:

when the line is solid with no spaces in between, that automatically rules out A) and C). and the shading is underneath the line so that rules out B) as well.

Hope this helped you!
