Given:
The objective is to find the slope of the straight line.
Step-by-step explanation:
The general equation to find the slope is,
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
Let's consider two coordinates from the graph.
![\begin{gathered} (x_1,y_1)=(0,0) \\ (x_2,y_2)=(-1,5) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/vkntgpzm55pvwg3z4qpo2sypzad5luyrxs.png)
On plugging the values in the equation of slope,
![\begin{gathered} m=(5-0)/(-1-0) \\ m=-5 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/kqmyei5ltxaoj3tm64aojyn9m9o4d4kz8x.png)
Hence, the slope of the straight line is -5.
