Finding the slope using two points:
The formula for slope is
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
In this case...
[tex]y_{2} =7\\y_{1} =6\\x_{2} =8\\x_{1} =4[/tex]
^^^Plug these numbers into the formula for slope...
[tex]\frac{7 - 6}{8 - 4}[/tex]
C) [tex]\frac{1}{4}[/tex]
^^^This is your slope
Hope this helped!
