It is 2. You flip the fraction and make it negative always to get perpendicular slopes. If it was like 3, you treat it as 3/1 and would make it -1/3.

Answer:

2

Explanation:

A line that is perpendicular will have a slope that is the opposite reciprocal of the given slope (flip the slope and change the sign)

So a line perpendicular to a line with slope -1/2 will have a slope of 2/1 or 2.
