find the function domain and range and the slope of the graph

The line end points are (4,3) and (-5,-2).
The value of x coordinates give the domain and values of y coordinates give the range.
Since point (4,3) lies on the line and point (-5,-2) does not lie on ther line.
Domain is,
[tex](-5,4\rbrack[/tex]Range is,
[tex](-2,3\rbrack[/tex]Determine the slope of line.
[tex]\begin{gathered} m=\frac{3-(-2)}{4-(-5)} \\ =\frac{5}{9} \end{gathered}[/tex]So slope is 5/9.
