Question

Find the distance between (-4,-3) and (-8,2)

Answer 1

The distance (r) between any two points (a,b) and (c,d) is :—

$r = \sqrt{{(a - c)}^{2} + {(b - d)}^{2} }$

Putting the values,

$\sqrt{ {( - 4 + 8)}^{2} + {( - 3 - 2) }^{2} }$

$r = \sqrt{16 + 25}$

$r = \sqrt{41}$

The distance between the points is √41
