Question 491481
find the distance between two points on a plane. The points are (9,5) and (-2,2)
:
The distance formula: d = {{{sqrt((x2-x1)^2 + (y2-y1)^2))}}}
Assign the given values as follows
x1 = 9; y1 = 5
x2 =-2; y2 = 2
;
d = {{{sqrt((-2-9)^2 + (2-5)^2))}}}
:
d = {{{sqrt((-11)^2 + (-3)^2))}}}
:
d = {{{sqrt(121 + 9))}}}
:
d = {{{sqrt(130))}}}
d = 11.4
