### 10-5 Planes in Space

We already know what a vector in a three dimensional setting looks like:

To find a vector ,normal or perpendicular, to the plane Ax + By +Cz = D, just plug the coefficients A, B, and C into the vector formula:

**EXAMPLE**

- given 3x - 8y + 5z = 24
- plug 3, -8, and 5 into the vector formula
- your answer should be

You can also determine a plane by using a **normal vector and a point**, as shown below:

To find a plane using a normal vector and a point P:

- *the vectors are perpendicular so their sum is 0

**EXAMPLE**

These are pictures from a **JACK'S MANNEQUIN **concert I went to in February. They're my favorite band and everyone should go listen to their music. Their rooted from **SOMETHING CORPORATE**, which is my other favorite band, because the lead singer was originally from SoCo. Andrew McMahon, the lead singer, fought and beat cancer, which i think is amazing and he's amazing so everyone should go buy his music NOW!

**JOEY YOU'RE UP NEXT!!!!**
