Question 250375
Parallel lines have identical slopes. 
{{{y=-(1/2)x}}}
The slope for this line is
{{{m=-1/2}}}
Use the point-slope form of a line with point (-4, -3) and slope m=-(1/2):
{{{y-yp=m(x-xp)}}}
{{{y-(-3)=-(1/2)(x-(-3))}}}
{{{y+3=-(1/2)(x+3)}}}
{{{y+3=-(1/2)(x)-(3/2)}}}
{{{y=-(1/2)(x)-(3/2)-(6/2)}}}
{{{y=-(1/2)(x)-(9/2)}}}
{{{ graph( 300, 300, -5, 5, -5, 5, -(1/2)x, -(1/2)(x)-(9/2)) }}}
