Answer:
distance d(A,B)=1
Step-by-step explanation:
we know that if we have given two point [tex]A(x_{1}, y_{1})[/tex] and [tex]and [/tex]x_{2},y_{2})[/tex] we have to find the distance between two points d(A, B)
then we can use following formula
d(A,B) =[tex]\sqrt((x_{2}-x_{1})^2+(y_{2}-y_{1})^2)\\=\sqrt((9-8)^2\\=\sqrt(1)\\=1
