Identify two coordinates on the graph
------------------------------------------------------------------------------------------
( 0, -1) and (3, 0)

------------------------------------------------------------------------------------------
Apply the formula for Slope
-------------------------------------------------------------------------------------------

$\boxed{ Slope = \frac{Y_2-Y_1}{X_2 - X1} }$

$\boxed {Slope = \frac{0-(-1)}{3-0}}$

$\boxed { Slope = \frac{1}{3} }$
