Find the Slopes of the lines whose inclinations are

(i) 450  (ii) 300  (iii) 900  


(i) 450
Solution:      
The slope of line = tan θ
The slope of the line = tan 450 = 1
The slope of the line is 1.

(ii) 300
Solution:
The slope of line = tan θ







(iii) 900
Solution:
Solution:
The slope of line = tan θ
The slope of the line = tan 900 = Not Defined

The slope of the line is Not Defined.
