Answer 1

The slope of a line is given by:

`m=(\Delta y)/(\Delta x)`

Choose two ordered pairs of values to find the slope. For instance, use (1,8) and (4,6).

Substitute these data into the equation for m:

`\begin{gathered} m=(8-6)/(1-4) \\ =(2)/(-3) \\ =-(2)/(3) \end{gathered}`

Therefore, the slope of the line is -2/3.
