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:


y-y1=(y2-y1)/(x2-x1)* (x-x1)

Here (x1,y1)=(0,-1) and (y2-y1)=(1/2,0)

Hence, equation of line=
y+1=(0+1)/(1/2-0)* (x-0)

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)
