Hey!
------------------------------------------------------
Looking at the graph we can see that the points are (-9, -3) (0, 9) (-5, -3) and (-2, 1)
------------------------------------------------------
Now, we can find the slope
[tex]\frac{9 - (-3)}{0 - (-9)} = \frac{12}{9} = \frac{4}{3}[/tex]
[tex]\frac{1 - (-3)}{-2 - (-5)} = \frac{4}{3}[/tex]
------------------------------------------------------
Hence, the slope of the table is 4/3!
------------------------------------------------------
Hope This Helped! Good Luck!
