Question

Choose the equation of the line passing through the point (-3, -1) and perpendicular to y =1/2 x + 3.

Answer 1

since you already know a point that is on the line you want, all you need now is the slope of the line that's perpendicular to y = (1/2)x + 3..
do you know the relationship between perpendicular slopes?

Answer 2

y = -2x +5
