Given:
Line A: 
Line B: 
Line C: 
Line D: 
To find:
Which lines are perpendicular
Solution:
General equation of a line:
y = mx + c
where m is the slope and c is the y-intercept.
Slope of line A = 
Slope of line B = 
Slope of line C = 2
Slope of line D = 
<em>Two lines are perpendicular if their slopes are negative reciprocal of one another.</em>


Negative reciprocal of
is 2.
Therefore line B and line C are perpendicular lines.
