Find the slope of the line perpendicular to the line y = (1/4)x - 7 Choose the most appropriate option.
A) 1 B) 2 C) -4 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 / 4. If m is the slope of the line perpendicular to the given line, then   m × (1/4) = -1   Solve for m   m = - 4   correct answer -4) -4
