Answer:
8
Explanation:
Use the Pythagorean theorem:
a^2+b^2=c^2
(You have to count the distance of x and y, then plug those number in the formula)
0^2+8^2=c^2
64=c^2
square root it
8=c
You can also use the distance formula
square root of (x2-x1)^2+(y1-y2)^2
square root of (-3-(-3))^2+(-2-(-10))^2
=8
(I'm pretty sure, if it's wrong I'm sorry)
