Answer:
[tex]\sf \boxed{\sf distance: \ 5 \ units}[/tex]
Explanation:
The points represented (marked blue) are (8, 5), (4, 2)
[tex]\sf Distance\ between \ two \ points : \sqrt{(x_2 -x_1)^2+(y_2 - y_1)^2 }[/tex]
Insert values:
[tex]\rigtharrow \sf \sqrt{(8-4)^2 + (5-2)^2}[/tex]
[tex]\rightarrow \rigtharrow \sf \sqrt{16 + 9}[/tex]
[tex]\rightarrow \rigtharrow \sf 5[/tex]
