Question

Geometry -

Find the distance between (1,-3) and (-8,6) approximated to 1 decimal place.
Select the correct response:
12.8
12.9
12.6
12.7

Answer 1

• D. 12.7

Explanation:

Use distance formula:

• 
  `d = √((x_1-x_2)^2+(y_1-y_2)^2)`

Substitute the coordinates and find the distance:

• 
  `d = √((1-(-8))^2+(-3-6)^2)=√(81+81) =√(162) =12.7`
