What is the distance between (-6, 8) and (-3, 9)?

Question

use the distance formula

Answer 1

Distance =√[(x₁ - x₂)² + (y₁ -y₂)²]

= √[(-6-(-3))² + (8-9)²]

= √[(-6+3)² + (-1)²] = √[(-3)²+ 1] = √[9 + 1] = √[10]

= √10

If you need an approximate, then use a calculator to determine the square root. To four decimal places, the values is 3.1623.

NOTE: it does not matter which point you use for (x₁, y₁). When you square the differences, the order of the points becomes irrelevant.
