Using only a compass & straight edge (classic style), draw a circle around any point on the line. All you need is the two tiny arcs crossing the line. Then taking the two places where your first arcs crossed the line as centers, draw two bigger circles around those points. Note that each circle will each cross the line at two points. You actually need just the two points from each center "toward" the other center. (Don't make the two second circles so big that the radius is greater than the distance between the two points (though this will still work). This will give you two arcs across the line, and they will intersect each other above and below the line. If you then take your straight edge and draw a line through your original line from one of those intersections to the other, this new line will be perpendicular to the original line.
Use the link to the Wikipedia article and look at the construction. It's actually the construction of a perpendicular through a line from a point off the original line, but check it out and note the green arcs, which would be your two second arcs from the two centers you found with your first circle. The blue line is the perpendicular to the original (the black) line.
m2=-1/m1 where m1=grad of the original line & m2=grad of the line perpendicular to the original line
There are infinitely many lines perpendicular to this line. All of them have the slope of -4/3, if that fact is of any help to you.
A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
A sole line can't be perpendicular. To be perpendicular, a line has to meet with another line, to form right angles on either side. Perpendicular is the exact opposite of parallel. Parallel: = Perpendicular: -|
Slope of a line perpendicular to x-y=16
The slope of the perpendicular is -(1/2) .

A horizontal line is perpendicular to a vertical line.
A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)
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.
To find the perpendicular line segment from a point to a line by folding paper, first, place the point on one side of the line and the line itself on the opposite side. Fold the paper so that the point aligns directly over the line, ensuring the fold creates a crease that intersects the line at a right angle. The crease represents the perpendicular segment from the point to the line, and its intersection with the line is the foot of the perpendicular. Unfold the paper to reveal the segment clearly.
To find the slope of a perpendicular line, take the negative reciprocal of the slope of the given line. (Flip the top and bottom of the fraction and change the sign.) The slope of 3 can be written as 3/1. The slope of a line that is perpendicular is -1/3.
A horizontal line is a line perpendicular to the vertical.
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
Given y = 2x the slope of that line is simply 2, A perpendicular line would have the negative inverse of 2, -1/2 or -.5 thus y = 2x is perpendicular to y = -.5x Y = -(1/Mx) + b is perpendicular to: Y= Mx + b
