    The line that intersects the x-axis at    -2 , 0
       and the y-axis  at   3, 0
       is a horizontal line passing through the origin
       the slope  m=0
       by definition the slope of a horizontal line = 0
                                 the slope of a vertical line  is undefined
        the equation       y   =  m x + b
                                     y  =  0 x + 0
          whatever values you give to x ,      y    will always =  0
