Question

On a coordinate plane, point A is located at (7, 4), and point B is located at (-8, 4). What is the distance between the two points? *

Answer 1

Explanation:

`Distance=\sqrt{(x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2)}\\\\ =\sqrt{(-8-7)^(2)+(4-4)^(2)}\\\\ =\sqrt{(-15)^(2)+0}\\\\=√(225) \\\\=15`
