#=color(blue)(sqrt(98#

#(-3,-2) = color(blue)((x_1,y_1)#

#(4,5) = color(blue)((x_2,y_2)#

The distance formula is

distance#=sqrt((x_2-x_1)^2 + (y_2-y_1)^2#

#=sqrt((4-(-3))^2 + (5-(-2))^2#

#=sqrt((4+3)^2 + (5 +2)^2#

#=sqrt((7)^2 + (7)^2#

#=sqrt(49 + 49#

#=color(blue)(sqrt(98#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
