Answer: The slope of the line is -4
Slope is given as
Slope = rise / run
Where rise = y2 - y1
Run = x2 - x1
Firstly, we need to pick an points on the table
(-7, 21) and (-6, 17)
Let x1 = -7, y1 = 21, x2 = -6 , and y2 = 17
[tex]\begin{gathered} \text{ Since, slope = }\frac{y2\text{ - y1}}{x2\text{ - x1}} \\ \text{Slope = }\frac{17\text{ - 21}}{-6\text{ - (-7)}} \\ \text{Slope = }\frac{-4}{-6\text{ + 7}} \\ \text{Slope = }\frac{-4}{1} \\ \text{Slope = -4} \end{gathered}[/tex]
