-1 is steeper
Since you know the negative signs in front numbers mean they are going in the negative directions. So the sign will not affect the steepness.
First do the absolute value of each, so they become 1 and 1/2.
slope of -1 can be interpreted as rise 1, run 1
slope of -1/2 can be interpreted as rise 1, run 2.
Now imagine you are going over a ramp with height as 1 and the distance be 1 and another ramp with the same height but with running through a distance of twice as much as the first ramp.
Clearly you can see the first ramp running through less distance but with the same height would be steeper.
So the answer is -1 is steeper.
Hope this helps!
