Question

Find the distance between the two points rounding to the nearest tenth (if necessary).)

(9,−5) and (0,−9)

Answer 1

9.8

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.
