What is the slope of the line containing (-2, 9) and (3, -1)?


\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}

We can find the slope using the following formula:-


\boxed{(y_2-y_1)/(x_2-x_1)}


\bigstar substitute the numbers in lieu of the letters:-


\boxed{(-1-9)/(3-(-2))}


\dagger On simplification,


\boxed{(-10)/(3+2)}


\dagger On further simplification,


\boxed{(-10)/(5)}


\dagger Which simplifies to


\boxed{Slope=-2}

Good luck with your studies.
