Question

What is the distance between points (10, 7) and (2, 7) on a coordinate plane

Answer 1

$\sf{Distance= \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}}\\\\= \sqrt{\left( 2 - 10 \right)^2 + \left( 7 - 7 \right)^2} \\\\ = \sqrt{ 64 + 0} \\\\ =\boxed{\bf{ 8}}$

The distance between the points (10,7) and (2,7) is 8.
