Chapter 9.6, Problem 1AYU

The distance $d$ from $P_1=\left(x_1,y_1\right)$ to $P_1=\left(x_1,y_1\right)$ is $d=$ _______. (p. 4)

To determine

To fill: Fill in the blank: The distance $d$ from $P_1 = (x_1, y_1)$ to $P_2 = (x_2, y_2)$ is $d = \_\_\_\_\_\_\_\_\_$.

Answer to Problem 1AYU

Solution:

$\sqrt{{(x_2 - x_1)}^2 + {(y_2 - y_1)}^2}$

Explanation of Solution

The distance $d$ from $P_1 = (x_1, y_1)$ to $P_2 = (x_2, y_2)$ is $d = \sqrt{{(x_2 - x_1)}^2 + {(y_2 - y_1)}^2}$.
