Use the pyathorem theorem and find the change in x and y to find the distance of the hypothenuse

$A^2 + B^2 = C^2$
Let A = the change in x
Let B = the change in y
Let C = the distance between the points

The change in x = $5-(-8) = 13$
The change in y = $-8 - 6 = -14$

$C^2 = 13^2 + -14^2$

$C^2 = 169 + 196$

$C^2 = 365$

$C = 19.1$ or 19 to two significant digits.

The distance between the two points is approximately 19
