bibby · Answer

distance formula = $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

bibby · Answer

plug in the coordinates.

(x1,y1)=y(-1 -11)
 (x2,y2)=(-1 -3)

@Analoha 
this problem is nothing but order of operations + plugging in

you have the fact that $\large d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$
and the fact that x1= -1 ||| y1= -11
x2 = -1 ||| y2 = -3
