            The  "solution"  in the post by  @josgarithmetic is  WRONG :   he incorrectly uses formula to calculate the slope.

            I came to bring a correct solution. 


At the given point (-3,-3/2), the slope is  (-3+1)*(-3+2) = (-2)*(-1) = 2.


Therefore, the equation of the straight line at this point is


     = 2*(x-(-3)),      (1)  

or

    2y + 3 = 4*(x+3),

    2y + 3 = 4x + 12

    4x - 2y = -9.                (2)


You may choose any of the equations (1) or (2) - they are EQUIVALENT.

Solved.
