Question

Consider the line whose equation is y=-1/2x+3
any line that is perpendicular to this line is

Answer 1

positive

Explanation:

for a line to be perpendicular to another line, the slope must be reciprocaled and if its positive it becomes negative (vice versa)

y = -1/2x+3 = Line A

y = 2x+3 = PERPENDICULAR to Line A
