a line that is perpendicular has a negative opposite slope of the original equation. 
So if your equation $y=-2x-8$, $m=-2$
The slope of the perpendicular line would be a negative reciprocal, so $m=-(-\frac{1}{2})=2$ with this, and your points (4.4), use the point slope form. $$\large y-y_{1}=m(x-x_{1})$$ plug in (4,4) as your (x,y) and m=2 as your slope. $$\large y-4=2(x-4)$$ I'll let you simplify and solve it :)

Do you understand how to solve the rest, @lastkings ?

is it y=2x+4?

You're almost right, but it's y= 2x -8+4
