Find the slope of the line, which makes an angle of 30° with the positive direction of y-axis measured anticlockwise.
what difference it will get when it become clockwise in place of aticlockwise.

slope of a line is equal to tan(theta). but theta is the angle made by the line from x-axis. so theta here will be 60°
thus, slope =60° = ✓3.
thus, slope =60° = ✓3.

Hey !!
If a line makes an angle of 30° with the positive direction of the y-axis measured anticlockwise, then the angle made by the line with the positive direction of the x-axis measured anticlockwise is 90° + 30° = 120°
Thus, the slope of the given line is
tan 120° = tan (180° - 60°)
= tan 60°
FINAL RESULT = -√3
GOOD LUCK !!
