# How do you find the distance between (11, 11), (-13,8)?

May 19, 2018

11, 11 is 11x +11y and
-13,8 is -13x +8y

#### Explanation:

If you plot this on a Cartesian x-y graph you will see that there is right angled triangle, formed by the equation

11x +13x and 11y - 8y resulting in a triangle 24x and 3y.

since we are interested in the distance only, we deal only with the absolute values.

distance d is then ${d}^{2}$ = ${24}^{2}$ + ${3}^{2}$

d = sqrt (576 +9

d = $\sqrt{585}$
