Question

Find the slope of a line that passes through the following pair of points: (-2,-5) and (-4,-9) m=

Answer 1

The general rule for the slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

then, in this case we have:

$\begin{gathered} m=\frac{-9-(-5)}{-4-(-2)}=\frac{-9+5}{-4+2}=\frac{-4}{-2}=2 \\ m=2 \end{gathered}$

therefore, the slope is m=2
