Only by coincidence. Two lines on a graph are perpendicular if and only if one slope is the negative reciprocal of the other: meaning that if one line has a slope of 3/2, the other would have to have a gradient of -2/3.

When is the product of the slopes of two perpendicular lines not equal to -1?
When the perpendicular lines are horizontal and vertical.
What must be true about the slopes of 2 perpendicular lines?
The slopes of two perpendicular lines are negative inverses of each other. In other words, the two slopes when multiplied together equal -1.
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
If the slopes of two lines are negative reciprocals the lines are perpendicular. true or false?
true (APEX)
If the slopes of two lines are negative reciprocals, the lines are perpendicular. true or false?
true (APEX)
If two lines are 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 the lines are perpendicular, their slopes are negative reciprocals.
How do you calculate parallel and perpendicular lines in a given plane?
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.
How do you use slope to determine if two lines are perpendicular?
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.
Do two lines that have slopes of 1 and -1 are perpendicular?

If two lines have slopes that are negative reciprocals of each other then they are if they have slopes that are the same then they are?
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
Is it true that two lines with different slopes are perpendicular?
No. Only lines that intersect at 90 degree angles are perpendicular. Any other lines that cross each other are simply intersecting lines.
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
If the product of the slopes of two lines equals -1 then the lines?
Are perpendicular to one another.
How do you know if two non-vertical lines are perpendicular?
They are perpendicular if their slopes are mutual negative reciprocals.
Is it possible for two lines with positive slopes to be perpendicular?
Is it possible for two lines with positive slopes to be perpendicular?
