Given:
The objective is to find the slope of the straight line.
Explanation:
The general equation to find the slope is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Let's consider two coordinates from the graph.
[tex]\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}[/tex]On plugging the values in the equation of slope,
[tex]\begin{gathered} m=\frac{5-0}{-1-0} \\ m=-5 \end{gathered}[/tex]Hence, the slope of the straight line is -5.
