Find the distance between the points (2.8) and (-1, 9). o √2 V10 NEXT QUESTION O ASK FOR HELP

Answer 1

The distance between two points can be calculated by the formula

`\begin{gathered} (x_1,y_1)=(2,8) \\ (x_2,y_2)=(-1,9) \\ d=\sqrt[]{(-1-2)^2+(9-8)^2} \\ \end{gathered}`
`\begin{gathered} d=√((-3)^2+(1)^2) \\ d=√(9+1) \\ d=√(10) \end{gathered}`
`The\text{ answer is }\sqrt[]{10}`
