Answer :
You need to use the distance formula [square root of (x2-x1)^2 + (y2-y1)^2]
square root of (0-(-2))^2 + (-6-4)^2
square root of 2^2 + (-10)^2
square root of 4+100
10.198 so it is 10.2
square root of (0-(-2))^2 + (-6-4)^2
square root of 2^2 + (-10)^2
square root of 4+100
10.198 so it is 10.2
