Find the distance between the points (2, 5) and (5, 9).
-
A.
4 units -
B.
5 units -
C.
12 units -
D.
14 units
Correct Answer: Option B
Explanation
Distance between two points (a, b) and (c, d) = (sqrt{(d – b)^{2} + (c – a)^{2}}
Distance between (2, 5) and (5, 9) = (sqrt{(9-5)^{2} + (5-2)^{2}})
= (sqrt{16 + 9} = sqrt{25} = 5 units)
