Answer:
C) √10
Step-by-step explanation:
The distance between two points can be solved using the distance formula (given below) where the distance is = √([tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}[/tex]
Using the two points given: (2, 8) and (-1, 9):
√([tex]\sqrt{(-1 - 2)^{2}+(9-8)^{2}[/tex] = √([tex]\sqrt{(-3)^{2}+(1)^{2}[/tex] = √10
