SOLUTION
The diagram below would be helpful in answering the question
From the diagram in the line graph above, I have made two points with coordinates (0, -3) and (5, 3)
The slope m becomes
[tex]\begin{gathered} m=\frac{3-(-3)}{5-0} \\ m=\frac{3+3}{5} \\ m=\frac{6}{5} \end{gathered}[/tex]
Hence the answer is option A
