| 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 x-axis at (-2,0) andy-axis at (0,4). So, it lies totally outside the window and so cannot be clipped.
