    the line is parallel to the equation y=-2x+5 means they have d same slope

    ok the equation is in d form y=mx+b where m is d slope.....so the value in front of x is the slope

    now since d equation of the line we are looking for has that same slope we are done

    well not done per say but almost there.......slope intercept form is y=mx+b

    y= -2(-4) + 5(-8) y = 8 + -40

    y=-4 and x=-8 i.e -8= -2(-4) +b

    all u do nxt is just take ur value of b and put it in dis equation which is d equation we are looking for. y= -2x+(the value of b u got)
