Good morning.

Morning
OpenStudy (luffingsails):
To find the distance between two points, use the distance formula:
square root ( (x1 - x2)^2 + (y1 - y2)^2)
square root( (8-8)^2 + (-6-3)^2) = square root(0^2 + (-9)^2)
square root(81) = 9.
So, C is the right answer.

Make sense?

You're welcome.

He's given you the equation for a distance between two points. You just have to plug in the numbers for (x,y)
OpenStudy (luffingsails):
Same method, Smart. Give the equation a try.
