Question

Can you help me please don’t go into full detail explaining, be a little vague, I pick up quick

Answer 1

`\begin{gathered} \tan\propto=(y)/(x) \\ \\ \tan\propto=(-√(7))/(√(5)) \end{gathered}`

Then, rationalize;

`\begin{gathered} \tan\propto=(-√(7))/(√(5))*(√(5))/(√(5)) \\ \\ \tan\propto=-(√(35))/(5) \\ \end{gathered}`
