Question

Find the length of the line segment that joins the points (2, 5) and (9, 8).

√10
√52
√58

Answer 1

The answer is the square root of 58.

I got this question right on an assignment.

Answer 2

distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,5)...x1 = 2 and y1 = 5
(9,8)...x2 = 9 and y2 = 8
now we sub
d = sqrt ((9 - 2)^2 + (8 - 5)^2)
d = sqrt ((7^2) + (3^2))
d = sqrt (49 + 9)
d = sqrt 58 <===
