Answer:
Distance between this two points is 3sqrt(2)
Step-by-step explanation:
A(-5,-6).............x1=-5, y1 =-6
B(-8,-9).............x2 =-8, y2 =-9
d(A, B) =sqrt((x2-x1)^2 +(y2-y1)^2)
d(A, B)= sqrt((-8-(-5))^2+(-9-(-6))^2)
d(A, В) =sqrt((-8+5)^2 +(-9+6)^2)
d(A, B) =sqrt((-3)^2 +(-3)^2)
d(A, B) =sqrt(9+9)
d(A, B)= sqrt(9*2)
d(A, B) =3*sqrt(2)
