Points A and B have the coordinates shown below.

marshall27 [118]

Answer:

Distance AB is <em>18.79 units</em>

Step-by-step explanation:

Given two points with coordinates as:

A= (-4,7)

B= (-12, -10)

To find:

Distance AB = ?

Solution:

To find the distance between two points with given coordinates, we can use Distance formula.

Distance formula is given as:

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

where $(x_1, y_1)$ and $(x_2, y_2)$ are the two coordinates whose distance is to be find out.

$x_1 = -4\\y_1 = 7\\x_2 = -12\\y_2 = -10$

$AB = \sqrt{(-12-(-4))^2+(-10-7)^2}\\\Rightarrow AB = \sqrt{(-8)^2+(-17)^2}\\\Rightarrow AB = \sqrt{64+289}\\\Rightarrow AB = \sqrt{353}\\\Rightarrow \bold{AB = 18.79\ units }$

Distance AB is <em>18.79 units</em>
