please I need help on this question I need the rise and the run graphed on the chart and the slope of the line in simplest form

we can calculate the slope with this formula
[tex]\begin{gathered} m=\frac{y2-y1}{x2-x1} \\ \end{gathered}[/tex]where (x2,y2) is a right point from (x1,y1)
i will choose the points (0,8) and (4,3) from the line
so (x2,y2)=(4,3) and (x1,y1)=(0,8)
[tex]\begin{gathered} m=\frac{3-8}{4-0} \\ m=\frac{-5}{4} \\ m=-\frac{5}{4} \end{gathered}[/tex]the slope is -5/4
