Question

Two points sit on a line with the following coordinates: P (3, 3) and Q (4, 8). Which is the distance from P to Q?
A. sqrt 10 B. sqrt 15 C. sqrt 23 D. sqrt 26

Answer 1

use the distance formula

Answer 2

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

Answer 3

Say that x1=3,y1=1,x2=4,y2=4 (the coordinates of the points). Then the distance will be:
\[d =\sqrt{(y2-y1)^2+(x2-x1)^2}\]

Answer 4

\[\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2 }\]

Your 2 points are

P (3, 3) and Q (4, 8).
(x1,y1) (x2,y2)

Answer 5

root over (4-3)^2+(8-3)^2
root over 1^2+5^2
