Question

Can you help explain how to solve this for me?

Answer 1

`d=√((y_2-y_1)^2+(x_2-x_1)^2)`
`\begin{gathered} d=√((-4-8)^2+(5--6)^2) \\ d=√(-12^2+11^2) \\ d=√(265)=16.28 \end{gathered}`

b.

`\begin{gathered} m=(x_2+x_1)/(2),(y_2+y_1)/(2) \\ m=((-6+5)/(2),(-4+8)/(2)) \\ m=(-(1)/(2),2) \end{gathered}`
