How do you work out the equation of a line perpendicular to another line when the coordinate where they cross is known?
There are two things you need to remember. First, given a line y=mx+b, where m is the slope and b is the y-intercept, the slope of the line perpendicular is going to be -1/m. Next, if you have the point where the lines cross, you want to use the point-slope form of a line to get the equation of the perpendicular line. Suppose the lines cross at (h,k). Then the point-slope form of the equation for the perpendicular line crossing at (h,k) will be (y-k)=-1/m(x-h). This can be brought into the slope-intercept form y=(-1/m)x + h/m + k.
What else can I help you with?
When you cross two number lines that are perpendicular?
Perpendicular lines cross each other at right angles
Where the x and y axis cross in a coordinate plane?
The x and y axis cross at (0,0) on the coordinate plane.
How can you use a right angle to classify another angle?
When lines met or cross at a right angle are perpendicular lines.
How are perpendicular lines similar and different to intersecting lines?
Perpendicular lines are specific kinds of intersecting lines. They both cross paths. Intersecting lines can cross paths in any way, but perpendicular lines have to cross at right angles.
What is cross products?
in mathematics the cross products are the binary operation on two vectors in a 3dimensional Euclidean space that results in another vector which is perpendicular to the containing the 2 inputs vector.
How does a perpendicular look?
Perpendicular lines are lines that cross one another at a 90° angle. They have slopes that are opposite reciprocals of one another. Perpendicular lines intersect each other.
Is perpendicular two lines that cross?
Not only that; to be "perpendicular", they have to cross at an angle of 90 degrees.
Will perpendicular lines on the the same plane ever touch?
Yes, two perpendicular coplanar lines will touch. If you have two lines that, by definition, form a 90 degree angle (i.e., they are perpendicular) and are both on the same plane, eventually they must cross at some point on that plane. They will have exactly one point in common. If, however, the lines were, by definition, "perpendicular skew" lines, they would never cross because the definition forbids it.
Is a cross perpendicular?
no
When you cross two number linre that are perpendicular to each otherand intersect at 0?
Yes and they are the x and y axes of the Cartesian coordinate plane and they intersect at the point of origin which is at (0, 0)
When you cross two number lines that are perpendicular to each other and intersect at 0 you get a?
Cartesian coordinate plane. The vertical line becomes the y-axis. The horizontal line is the x-axis.
What is formed when two perpendicular lines cross?
When two perpendicular lines cross, a right angle is formed.
When you cross two number lines that are perpendicular?
Perpendicular lines cross each other at right angles
What is perpendicular line?
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: -|
Two lines are perpendicular if they are parallel and cross?
Parallel lines are never perpendicular. Perpendicular lines are co-planar and cross at right angles.
What is Perpendicular and Parallel?
Perpendicular is when two lines cross... Parallel is when two lines never meet.... _____________ _____________ = PARALLEL LINES If they cross they are perpendicular, if they don't, they are parallel.
Where the x and y axis cross in a coordinate plane?
The x and y axis cross at (0,0) on the coordinate plane.
