Ex10.1, 7 Find the slope of the line, which makes an angle of 30 with the positive direction of y-axis measured anticlockwise. The line makes angle of 30 from positive y axis Hence it makes angle of (90 + 30 ) from positive x axis i.e. 120 from positive x axis Hence = 120 Slope = m = tan = tan120 = tan (180 60 ) = tan 60 = 3 Hence, Slope of line = 3
