No but if the two lines are parallel then they will have the same slope.

They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x

If two nonvertical lines are perpendicular, then the product of their slope is -1.An equivalent way of stating this relationship is to say that one line is perpendicular to another line if its slope is the negative reciprocal of the slope of the other. For example, if a line has slope 3, any line having slope - 1/3 is perpendicular to it. Similarly, if a line has slope - 4/5, any line having the slope 5/4 is perpendicular to it.

That depends on the specific situation. You may want to measure angles (perpendicular lines are at a right angle, i.e., 90Â°). If you have equations for line, write them in the slope-intercept form. Parallel lines have the same slope. If lines are perpendicular, the product of their slopes is -1.

No, parallel lines have exactly same slope Perpendicular line have a slope that is negative reciprocal of each other that is if m = slope of line then slope of perpendicular line is -1/m

No, lines have the same slope if and only if they are parallel to each other.

For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.

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.

When the lines are horizontal and vertical. (slope of zero) (undefined slope)

Actually it IS. perpendicular lines have opposite reciprocal slopes and parallel lines have the same slope.

The slope of parallel lines are the same, but the slope of perpendicular lines are negative reciprocals of each other.

All parallel lines have a zero slope.

Two lines with the same slope are parallel.

No because two lines with the same slope but with different y intercepts are parallel lines. Perpendicular lines meet each other at right angles.
