SOLUTION
The picture below would help us find the slope easily
From the image above, I have made two points
(0, 7) and (2, 1)
The slope m can be gotten from these points as follows
[tex]\begin{gathered} m=\frac{1-7}{2-0} \\ m=-\frac{6}{2} \\ m=-3 \end{gathered}[/tex]
Hence the slope is -3, option B
