Question

Find the distance between A(2, -9) and B(-5, 7) on a coordinate plane d=?

Answer 1

Answer:

$d=17.4642$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance d:

$d=\sqrt{(-5-2)^2+(7-(-9))^2}$

$d=\sqrt{(-7)^2+(7+9)^2}$

$d=\sqrt{49+(16)^2}$

$d=\sqrt{49+256}$

$d=\sqrt{305}$

$d=17.4642$
