Answer:
The correct option is:
 D. y+5=2(x+2)
Explanation:
The equation of the line passing through (x1,y1) and (x2,y2) is:
 

Here (x1,y1)=(0,-1) and (y2-y1)=(1/2,0)
 Hence, equation of line= 

 equation of line= y+1=2(x)
which can also be written as:
 y+5=2x+4 (adding 4 on both sides)
 =2(x+2)
Hence, the correct option is:
 D. y+5=2(x+2)
