Our x2 and x1 is 4 and -5, respectively.

Similarly, our y2 and y1 is -9 and 2, respectively. Now plug them in:

\(d=\sqrt{[4-(-5)]^2+[-9-2]^2}\)

Can you solve that?

 

You are very welcome!

[  ( 4 - (-5)]^2  =  [ 4 + 5]^2  = 9^2  =  81     (1)

 

[ ( -9 - 2 ]^2  = [ -11]^2 = 121    (2)

 

Add (1) and (2), NSS

 

Take the square root of this sum and that will be your answer
