Question

find the distance between ( -1,3 ) and ( -7,5)

Answer 1

x2-x1= -7-(-1)
=-6
y2-y1= 5-3
=2
the distance is (-6,2)
root{(-6^2)+4}
=root{40}
=6.32

Answer 2

two points were (-1,3) and (-7,5)

now according to formula of distance

$\sqrt{(-1-(-7))^{2}+(3-5)^{2}}$

√(-1+7)²+(2)²

√6²+4

√36+4

√40=√2X2X2X5

=2√10units is the answer
