What can be said regarding a line if its slope is
(i) If the slope of the line is zero it means
M = tan θ
M = tan 0
Since, m = 0
So, The line is parallel to x - axis .
(ii) If the slope of the line is positive it means
Since θ is an acute
So, The line makes an acute angle with the positive x - axis .
(iii) If the slope of the line is positive it means
Since, θ is an obtuse
So, The line makes an obtuse angle with positive x - axis .
