Triangle knm is what is true about the sides of knm

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

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?
