Question

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

Answer 1

Hey there, you can solve this using the distance formula! 

$Distance = \sqrt{(x_{2}- x_{1})^2+(y_{2}- y_{1})^2}$

Where $x_{1}$ = 10
            $x_{2}$ = 2
            $y_{1}$ = 7
            $y_{2}$ = 7

So...
$Distance = \sqrt{(2- 10)^2+(7- 7)^2}$
$Distance = \sqrt{(-8)^2+(0)}$
$Distance = \sqrt{64}$
Distance = 8 units
