The slope formula is givenb by:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
To get the slope from the graph, we will pick out two points lying on the line:
Point 1: (x, y) = (-6, 10)
Point 2: (x, y) = (0, -8)
We will then proceed to use these points to calculate the slope, we have:
![\begin{gathered} m=(-8-10)/(0--6)=-(18)/(6) \\ m=-3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/17zlbkz1mv5oz5x7jsyu60mq5t1brsn7oe.png)
The slope (m) = -3
