Find the equation of LINE which is inclined at 30 degree with the negative direction of the y axis and cuts off an intercept of 2 on the x-axis in the negative direction of x-axis

If the line makes 30° with negative y-axis and making intercept of length 2 with negative x-axis,
then as shown in figure, angle made by the line with negative x-axis is 60°.
 
Hence slope m = -tan60 = -√3  and the line passing through P(-2,0)
 
Equation of line y = mx + c , where m is slopeand c is y-intercept
 
hence equation of line, y = -√3 x + c ...............(1)
since the line passing through the point P( -2, 0),   we have,   0 = -√3 (-2) + c   or c = -2√3
 
hence equation of line is y = - √3x - 2√3   or √3x+y+2√3 = 0
