Lesson 14.1 distance in the coordinate plane answer key

Sagot :

The distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], is used to find the distance between two points on a coordinate plane.

What is the Distance Formula?

The distance formula, [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex], is used to find the distance between two points on a coordinate plane.

For example, given the following points on a coordinate plane:

  • A(2, 3) - (x1, y1)
  • B(5, 6) - (x2, y2)

Using the distance formula, we would calculate the distance as:

AB =√[(5−2)² + (6−3)²]

AB = √[(3)² + (3)²]

AB = √18

AB = 4.2
