Answer:
10
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
[tex]\sqrt{(x2-x1)^2+(y2-y1)^2} \\[/tex]
Substitute the actual values of the points into the distance formula.
[tex]\sqrt{(9-1)^2+(8-2)^2}[/tex]
Simplify,
[tex]\sqrt{100}[/tex]
Rewrite
[tex]\sqrt{10^2}[/tex]
Pull terms out from under the radical, assuming positive real numbers.
