Answer:

9.8

Step-by-step explanation:

First you would use the distance formula:

  • √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the points into the formula, so x₂ would be 0 and y₂ would be -9

  • √[(0 - 9)² + (-9 + 5)²]
  • Reminder: two negatives make a positive so (-9 - -5) changes to (-9 + 5)

The answer would be 9.8488578018 plugged into the calculator or 9.8 rounded to the tenth place.
