Question

Find the slope of a line passing through each pair of points (0,6) and (3,0)

Answer 1

The slope of a line, m, that passes through a pair of points is given by the ratio between the variation in y and the variation in x:

$\begin{gathered} m=\frac{\Delta y}{\Delta x} \\ m=\frac{0-6}{3-0} \\ m=\frac{-6}{3} \\ m=-2 \end{gathered}$

So, the slope of the line is m=-2
