Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
The horizontal distance from points (5,-18) and (8,-17) is 3 because it is 3 units from 5 to 8. The vertical distance is 1 since it is one unit from -18 to -17. Now we can use the equation [tex]a^{2}+b^{2}=c^{2}[/tex] where a=3 and b=1 and c is the distance that you are looking for:
[tex]a^{2} +b^{2} =c^{2}\\3^{2} +1^{2} =c^{2}\\9+1=c^{2}\\10=c^{2}\\\sqrt{10}=c[/tex]
