What are the coordinates of the midpoint of ab? ,1/2) /2,-1) ,-3/2) /2,-2)

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

Aquadratic equation in standard from is written ax^2= bx+c, where a,b and c are real numbers and a is not zero?
