You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
They are perpendicular if their slopes are mutual negative reciprocals.
Are perpendicular to one another.
Yes, as long as the negative slopes are both equal.
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.

If two lines are parallel, they have the same slope.(And if they are perpendicular, the product of their slopes is minus one - unless one line is horizontal and the other vertical.)
When the perpendicular lines are horizontal and vertical.
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
Are perpendicular.
They are perpendicular if their slopes are mutual negative reciprocals.
Are perpendicular to one another.
Is it possible for two lines with positive slopes to be perpendicular?
