hi
 let's take the  co-ordinates  of the 2 points given in graph...
      1st one - (-2,3)
      2nd one - (-1 , -4)

  now the slope of a function can be found by formula....$$slope = \frac{ Y _{2} - Y _{1} }{X _{2} -X _{1} }$$ 

here,
       y2 = -4
       y1 = 3
       X2 = -1
       x1 = -2

so....the slope can be written as....$$slope = \frac{ (-4) - 3 }{ (-1) -(2)}$$

wt is the slope then ???
