$s = 7, 28 unit$ $s=7,28" unit"$

Explanation:

$A = (- 7, 5)$ $A=(-7,5)$
$B = (0, 7)$ $B=(0,7)$
$A_{x} = - 7$ $A_x=-7$
$B_{x} = 0$ $B_x=0$
$A_{y} = 5$ $A_y=5$
$B_{y} = 7$ $B_y=7$

$distance between two points can be calculated using formula:$ $"distance between two points can be calculated using formula:"$
$s = \sqrt{{(B_{x} - A_{x})}_{x}^{2} + {(B_{y} - A_{y})}_{y}^{2}}$ $s=sqrt((B_x-A_x)^2+(B_y-A_y)^2)$

$s = \sqrt{{(0 + 7)}^{2} + {(7 - 5)}^{2}}$ $s=sqrt((0+7)^2+(7-5)^2)$

$s = \sqrt{7^{2} + 2^{2}}$ $s=sqrt(7^2+2^2)$

$s = \sqrt{49 + 4}$ $s=sqrt(49+4)$

$s = \sqrt{53}$ $s=sqrt53$

$s = 7, 28 unit$ $s=7,28" unit"$
