Answer:
7.8
Step-by-step explanation:
distance formula :
where the x and y values are derived from the given points
here the given points are (11,3) and (6,9)
<u>assigning variables</u>
(x1,y1) = (11,3) so x1 = 11 and y1 = 3
(x2,y2) = (6,9) so x2 = 6 and y2 = 9
<u>plugging in values into formula</u>
recall formula
==> plug in x1 = 11 , y1 = 3 , x2 = 6 and y2 = 9
==> subtract values in parenthesis
==> evaluate exponents
==> add 25 and 36
( approximately )
