Find the slope of the line perpendicular to the line y = (1/2)x - 7 Choose the correct choice from the following choices.
A) 1
B) 2
C) -2
D) 4
E) 5
Two lines are perpendicular if the product of their slopes is equal to -1. The slope of the given line is equal to 1 / 2. If m is the slope of the line perpendicular to the given line, then   m × (1/2) = -1   Solve for m   m = - 2   correct answer -2) -2
