## What is the intersection of two planes?

The intersection of two planes is a line. If the planes do not intersect, they are parallel.

**How do you find the point of intersection of a line and a plane?**

c) Find all points of intersection of P with the line x = t, y =4+2t, z = t. Answer: a) To find the intersection we substitute the formulas for x, y and z into the equation for P and solve for t. The line is contained in the plane, i.e., all points of the line are in its intersection with the plane.

### How do you find a point on a plane?

Set any two of your variables x,y,z to zero and solve for the other. For example, if x=0 and y=0 then the equation gives z=−D/C. So if C≠0 then a point on your plane is (0,0,−D/C).

**How do I find the point of intersection of two lines in Excel?**

To find intersection of two straight lines:

- First we need the equations of the two lines.
- Then, since at the point of intersection, the two equations will have the same values of x and y, we set the two equations equal to each other.
- We substitute that x value in one of the line equations and solve it for y.

#### How do you find the point of intersection between a line and a plane?

Finding the intersection of a line and a plane

- substitute the values of x, y and z from the equation of the line into the equation of the plane and solve for the parameter t.
- take the value of t and plug it back into the equation of the line.

**How do you find a point on a line?**

To find points on the line y = mx + b,

- choose x and solve the equation for y, or.
- choose y and solve for x.

## How do you find the intersection of a sphere with a YZ plane?

To find the intersection with the yz-plane, we set x = 0: (y +6)2 + (z – 4)2 = 21, x = 0, a circle in the yz-plane with center (0, -6, 4) and radius V21. 15. The radius of the sphere is the distance between (4, 3, -1) and (3,8,1): r = V(3 – 4)2 + (8 – 3)2 + (1 – (-1)]2 = 130.

**Can line and plane intersect at exactly two points?**

If a line intersects a plane that does not contain it, then it intersects the plane in exactly one point. Any three points lie in at least one plane, and any three points not on the same line lie in exactly one plane. If two planes intersect, their intersection is a line.

### What is the formula of the intersection of two lines?

Method 1 of 2: Finding the Intersection of Two Straight Lines Remember, you can cancel out terms by performing the same action to both sides. Start with the basic equation y = mx + b . Set the right sides of the equation equal to each other. Write a new equation that represents this. Solve for x. Choose the equation for either line. Check your work.

**What is the formula for the point of intersection?**

Point of intersection means the point at which two lines intersect. These two lines are represented by the equation a1x2 + b1x + c1= 0 and a2x2 + b2x + c2 = 0 respectively. Given figure illustrate the point of intersection of two lines.

#### How do you name the intersection of two lines?

The exact place of intersection between two lines is called the “point” or “point of intersection” in geometry. A line is defined as a geometrical object that is straight as well as infinitely thin and infinitely long.
