What is the distance between (3, - 8) and (0, - 2)

The answer is 3√5. You use the distance formula: √ ((x2-x1) ^2 + (y2-y1) ^2)

You would use the distance formula sqrt ((x2 - x1) ^2 + (y2 - y1) ^2)

sqrt ((0-3) ^2 + (-2--8) ^2)

sqrt ((-3) ^2 + (6) ^2)

sqrt (9 + 36)

sqrt (45)

simplified 3sqrt5
