Question

Find the distance between (5, 9) & (-7, -7). Round to the nearest tenth.

Answer 1

20.0 units

Explanation:

`\boxed{distance = \sqrt{ {(y1 - y2)}^(2) + {(x1 - x2)}^(2) }}`

Distance between (5, 9) and (-7, -7)

`= \sqrt{( - 7 - 9)^(2) + ( - 7 - 5)^(2) }`

`= \sqrt{( - 16)^(2) + ( - 12)^(2) }`

`= √(256 + 144)`

`= √(400)`

= 20 units
