The formula for the distance between two points is:
[tex] \sqrt{(x_{2} - x_{1})^{2} + (y_{2}-y_{1})^2[/tex]
let (3,5) be x1 and y1, respectively and
(2,3) be x2 and y2, respectively
just substitute the numbers
SOLUTION:
[tex] \sqrt{(2-3)^2 + (3-5)^2} [/tex]
[tex] \sqrt{(-1)^2 + (-2)^2} [/tex]
[tex] \sqrt{5} [/tex]
