Write the equation of the line if m = -3/2 and b= 16

Find the center and the radius of the circle with the equation: x^2-2x+y^2+4y+1=0?

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

The length of the line segment ac is 8x-9 what is the value of x
