We have to find the slope of a linear function that passes through the points (-2,-5) and (-1,-6).
For doing so, we will use the formula:
![m=(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/78uaqhwt0aws3qfwxigaftpihnmb1gzxtp.png)
where (x₁,y₁) and (x₂,y₂) are two points of the line. Replacing we obtain that:
![m=(-6-(-5))/(-1-(-2))=(-6+5)/(-1+2)=(-1)/(1)=-1](https://img.qammunity.org/2023/formulas/mathematics/high-school/jp4h833e8ksalxptkw5hn9rdavnlawlrcx.png)
This means that the slope of the linear function is -1.
