Question

Find the distance between two points (1, 1)and (3 ,2)

Answer 1

Answer:

Find the distance between (-1, 1) and (3, 4).

This problem is solved simply by plugging our x- and y-values into the distance formula:

D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−√=

=16+9−−−−−√=25−−√=5

Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.

If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:

(x1+x22,y1+y22)

Answer 2

Step-by-step explanation:

A(1,1) and B(3,2)

Using distance formula

AB=

$\sqrt{(x1 - x2) + (y1 - y2)}$

Putting values

AB=

$\sqrt{(1 - 3)^{2} + (1 - 2)^{2} }$

$\sqrt{( - 2)^{2} + ( - 1)^{2} }$

$\sqrt{4 + 1}$

$\sqrt{5}$
