Help ! i should really pay attention in class

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2

If x-1 and x+3 are the factors of x3+10x2+ax+b find a and b
