Question

Given the Points A at (8 5) and B at (-1, -2) determine AB

Answer 1

Given the Points A at (8 -5) and B at (-1, -2) determine AB

Remember that the distance between two points is given by the formula

`d=\sqrt[]{(y2-y1)^2+(x2-x1)^2}`

substitute the given values

`AB=\sqrt[]{(-2+5)^2+(-1-8)^2}`
`\begin{gathered} AB=\sqrt[]{(3)^2+(-9)^2} \\ AB=\sqrt[]{90} \end{gathered}`

AB is option B
