Question

What is the distance between the points (4,3) and (-6,3) ???

Answer 1

You have to use the distance formula:

$\sqrt{(-6-(-4))^{2} + (3-3)^{2} }$
$\sqrt{(-2)^{2} + (0)^{2}}$
$\sqrt{4}$
2

The distance between those points is 2<span />

Answer 2

(x1 , y1) (x2 , y2 )
these are two coordinates 
the distance between them is 
square root of  [ (x2 minus x1) to the square plus ( y2 minus y1) to the square }
for u si square root of { -6-4) to the square + (3-3) to the square]
