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.

OpenStudy (luffingsails):

Make sense?

OpenStudy (anonymous):

yes thank you

OpenStudy (luffingsails):

You're welcome.

OpenStudy (anonymous):

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.

OpenStudy (anonymous):

okay
