Question

Use the distance formula to find the distance between the pair of points (8,5) and (-1,3)

Answer 1

we have the following;

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

replacing:

`\begin{gathered} d=√((-1-8)^2+(3-5)^2) \\ d=√((-9^2+(-2)^2) \\ d=√(81+4) \\ d=√(85)=9.22 \end{gathered}`

therefore, the answer is 9.22 units
