A. 
1 degree

B. 
1 radian

C.  45 degrees

A. 
(0, 1) and (3,3)

B. 
(0,1) and (2,3)

C.  (0, 1) and (4, 5) 
D.  none of the above 
Option: B Explanation :
The equation of the line joining (1, 0) and (4, 5) is x  y + 1 = 0. This cuts the window boundaries x = 0 and y = 3 at the points (0, 1) and (2,3) respectively.

A rectangle is bound by the lines x = 0; y = 0; x = 5 and y= 3.
The line segment joining (1, 1) and (4, 2) if clipped against this window will connect the points
A. 
(0, 1) and (3, 3)

B. 
(0, 1) and (2, 3)

C.  (1, 1) and (4,2) 
D.  none of the above 
Option: C Explanation :
A point (x, y) will be inside the window, if 0 < x < 5 and 0 < y < 3. So, the points (1, 1) and (4, 2), both lie within the window. So, it is already clipped

A rectangle is bound by the lines x = 0; y = 0; x = 5 and y = 3
The line 2x  y + 4 = 0, if clipped against this window will connect the points
A. 
(0, 1) and (3,3)

B. 
(0, 1) and (2, 3)

C.  (1,2) and (3, 4) 
D.  none of the above 
Option: D Explanation :
This line cuts the xaxis at (2,0) andyaxis at (0,4). So, it lies totally outside the window and so cannot be clipped.
