#### Find the equation of a plane

## What is the equation for the XY plane?

Similarly, the y-z-plane has standard equation x = 0 and the x-z-plane has standard equation y = 0. A plane parallel to the x-y-plane must have a standard equation z = d for some d, since it has normal vector k. A plane parallel to the y-z-plane has equation x = d, and one parallel to the x-z-plane has equation y = d.

## Is the equation of a plane unique?

As with equations of lines in three dimensions, it should be noted that there is not a unique equation for a given plane. The graph of the plane -2x-3y+z=2 is shown with its normal vector.

## What is a vector equation of a plane?

From the video, the equation of a plane given the normal vector n = [A,B,C] and a point p1 is n . p = n . p1, where p is the position vector [x,y,z].

## How do you find the normal of a plane?

Thus for a plane (or a line), a normal vector can be divided by its length to get a unit normal vector. Example: For the equation, x + 2y + 2z = 9, the vector A = (1, 2, 2) is a normal vector. |A| = square root of (1+4+4) = 3.

## How do you find the distance from a point to a plane?

Therefore, the distance from point P to the plane is along a line parallel to the normal vector, which is shown as a gray line segment. If we denote by R the point where the gray line segment touches the plane, then R is the point on the plane closest to P. The distance from P to the plane is the distance from P to R.

## What is the distance between two planes?

Definition. The distance between two planes is equal to length of the perpendicular lowered from a point on a plane.

## How do you find the distance from a point to a line?

Correct answer:To find the distance, use the formula displaystyle distance = frac{|ax_{0}+by_{0}+c |}{sqrt{a^2 + b^2 }} where the point is and the line is. displaystyle y = -frac{2}{3} x+8 add to and subtract 8 from both sides. displaystyle 3y +2x – 24 = 0 Now we see that displaystyle a = 2, b = 3, c = -24.

## What is a symmetric equation?

The symmetric form of the equation of a line is an equation that presents the two variables x and y in relationship to the x-intercept a and the y-intercept b of this line represented in a Cartesian plane. The symmetric form is presented like this: xa+yb=1, where a and b are non-zero.

## How do you define a plane?

In mathematics, a plane is a flat, two-dimensional surface that extends infinitely far. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
