Find the slope of the line that passes through (6, 9) and (9, 5).

`\diamond\large\blue\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}\diamond`

`\boxed{\\\begin{minipage}{3cm}\xrightarrow {slope\:formula\:below} \\ $\displaystyle(y_2-y_1)/(x_2-x_1)$ \\ \end{minipage}}}`

Substitute 5 for y₂, 9 for y₁, 9 for x₂ and 6 for x₁:-

`\boxed{(5-9)/(9-6)}`

On simplification,

↬
`\boxed{(-4)/(3)}`

►So we conclude that the slope of the line is

►
`\boxed{-(4)/(3)}` ◀︎

Good luck.
