Question

What is the distance between W(3, 1) and X(-2,-5)? Round to the nearest tenth.

10

A. 61.0
B. 3.3
C. 2.2
D. 7.8

Answer 1

D. 7.8

Explanation:

Distance formula:
`\sqrt{(x_(2) - x_(1))^2 +( y_(2) - y_(1))^2 }`

Substituting (-2 - 3)² + (-5 - 1)²

Distance =
`√((-5)^2 + (-6)^2)`

Distance =
`√(25 + 36)`

Distance = 7.8
