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

Answer:

Step-by-step explanation:

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