The first number is the x co-ordinate and the second is the y co-ordinate. As both y co-ordinates are 0 then the points are both on the x axis and they will be 3-(-8) apart which is 11.

find the distance between (3,0) and (-8, 0)
The distance formula is highlight%28d=sqrt%28%28x2-x1%29%5E2%2B%28y2-y1%29%5E2%29%29
(x1,y1)=(3,0) and (x2,y2)=(-8,0)
d=sqrt%28%283-%28-8%29%29%5E2%2B%280-0%29%5E2%29
d=sqrt%28%283%2B8%29%5E2%2B%280%29%5E2%29
d=sqrt%28%2811%29%5E2%2B0%29
d=sqrt%28121%29
highlight%28d=11%29
:
Note, when both the x's or y's are 0 as in this case you can take the absoulte value of their difference rather than using the distance formula, but the distance formula works every time.
Here's what I mean:
d=abs%283-%28-8%29%29
d=abs%283%2B8%29
d=abs%2811%29
highlight%28d=11%29
